Hi, after examining a picture showing U 93's gun (below, right) i finally found evidence that the "round shadow" on the gun's pedestal (see previous post) is definitely a hole.
Magnifying another picture of U 48's gun (below, left) I found another round shadow on the starboard side of the gun's pedestal: is it a hole or a shadow? In case it's a hole this would account for (at least) 2 holes in the pedestal: one at  5 and the other at ?7 or 9 hr.
What do you think of that? I definitely need your help!

I believe the hole is for a grease nipple.

Ha! good one, Simon!
I Just checked my database of pedestal pictures (hahahahahaha ;D ) and found the evidence I was after! below Right: the starboard side of an unidentified U-boat gun's pedestal: the same faint circular outline i had found on the port side of another pedestal's picture i had posted previously (below, Left): the holes (starboard and port) on U48's pedestal match perfectly with the outlines found on two different U-boat gun pedestals. So, the holes were there and  it looks like they had covers too! Moreover, the starboard side hole seems to be located after than the port side one: let's say the port one's at 8 and the starboard's at 5 hr, but perspective might be deceiving. I am very happy of this finding and hope that it can be useful to the Uboat modellers community (especially those modellers working with larger scales)

Hey! It's been a while. I've been unwell lately and am slowly recovering. This meant hitting the pause button for my project. There was something, however, that i wanted to share with you, which is the blog showing the details of my build, what i've been able to achieve over the years, with plenty of description and research. Though the blog's been active from 2014, i never tried to advertise the site because i had planned to do that once the 8.8 was ready, but life's short and it's probably like some among you would enjoy my work and benefit from what i have been experiencing and learning. After all it's just a matter of sharing things and experiences and i dont want mine to be wasted.
In the "about" section you will find the story of my project and a few words of appreciation for the AMP forum and for all of you, Gentlemen. I hope you'll enjoy my efforts.

Hi, I am still completing the pieces of the gun sight superstructure and I need some advice about a gun component, a bar parallel to the main axis of the gun tube which is placed right on top of the after section of the tube, linking to the base of the sight (Pic 1, arrows). Was it a stabilizer? Do you have a name for it? As far as I know there were at least two main variants of the 8.8 cm naval gun equipping U-Boats. One variant sported the bar and the other didn't. Artworks and technical drawings usually don't show the bar. (Pic 1, bottom)


http://cubeupload.com/im/SGm/Pic1.jpg


My problem is trying to understand which gun variant equipped U 48. Some pictures don't seem to show the bar (Pic 2), even the close-up on the left apparently doesn't show it, at least this is what my eye catches:


http://cubeupload.com/im/SGm/Pic2.jpg


While another picture of U48, which i compared to a beautiful closeup of U 564's gun, seem to confirm the same gun configuration as U 564 (Pic 3) 


http://cubeupload.com/im/SGm/Pic3.jpg


Am puzzled. It is possible that U 48 had been equipped with the two different variants in different stages of her career? Which variant should i go for: "bar" on "non-bar"?

Hi SG,

Really glad to hear you are recovering, my friend.

I have seen a photo of U 47 after the Scapa Flow raid just as the boat went into refit. The photo shows that the first thing they did was remove the 88mm by crane even before the crew went on leave. I am not sure if the same 88mm was then fitted back at the end of the refit. Or they may have then fitted a completely different 88mm which may have been new or overhauled.

The point I am trying to make is that it is likely that U 48 had quite a few different 88mm guns during its illustrious career.

Can I ask when are you depicting U 48?

Sending my best to you and everyone in Italy.

Best regards,

Dougie

Hi Dougie! first of all thank you for the wishes and for the kind message regarding the virus spread you did with Wink. We're living difficult times, shutdown, isolation, but am confident: all is cyclic in nature, there's always calm after a storm. So let's wait and take all the precautions not to get infected, there's nothing more we can do actually.


Yes it's probably like that U48 changed a number of 8.8s. that was my guess also, your input is crucial to confirm it, so double thank you. I am depicting U48 in the period june-October 1940 (sixt to ninth war patrol, under Rosing or Bleichrodt). In that period the boat sported the lateral trunks on her conning tower.


I've been studying chronology of pics as far as possibile and i noticed three streaks of ?grease/rust on the port side of the gun breech (visible in picture 3, previous post, taken at sea while moving a torpedo from the underdeck stowage to the torpedo room). The same stained breech is also visible in the picture where the sailors show the attack computer at the end of Bleichrodt command (picture below). So that same gun with "the bar configuration" was there during the period U48 was equipped with the trunks.

http://cubeupload.com/im/SGm/U48Calculateur.jpg


In this period U48 might have sported the 8.8 version with the "bar" as in pic 3 of my previous post, so I think am gonna be adding it to the 400th scale gun. A propos, any idea of what the bar is and what's its correct name? a stabilizer, a mere protected connector to the sight acting as a pedestal as well, since it bridges from the sight to the aiming device?.
I'll keep updating this thread as i take some more pictures of my progress. The aiming block pieces are nearly completed, they are SMALL. A few examples:

http://cubeupload.com/im/SGm/elevation.jpg

http://cubeupload.com/im/SGm/IMG1829.jpg

http://cubeupload.com/im/SGm/IMG2076.jpg

Then i'll be trying to bring it all together to buid a full gun tube. Let's see what i can get.
Stay safe. Keep modelling and researching, all my best

SG

Hi SG,

Well done on noticing the rust stains to work out the chronology. Dating photos is quite fun and using things like rusts stains or which base it is (Lorient or Kiel for example) really helps to find out if features on a boat were there at a specific time.

I am not sure about the bar as the 88mm is beyond what I normally research. I guess what is important is to work out if it has some form of actual function. Do you think there was some form of connector inside the bar?

Cheers,

Dougie

Dougie, I totally agree with you. Photographic research is funny, it is sometimes frustrating when pictures lack that perfect angulation you need or when something or someone gets in between and hides the detail you're after (those sailors with the attack computer for example ;D ) but yes, overall very intriguing.


The bar: no ideas, just mere speculation due to the fact that it connects the lead sight with the aiming device. The best book about naval armaments i found is Miroslaw Skwiot's "German Naval Guns 1939-1945". A spectacular book and very thorough, plenty of fine pictures, 3d artwork and technical drawings, which i recommend. The book however takes for granted the reader's knowledge of weapons terminology and gun components and thus lacks such information. Some 8.8 gun terminology can be found in the type VII volume of Anatomy of the ship, but that's far from being thorough. I am no expert of guns either and found myself confronted by a gun that has become "a model in a model": i wish i'd known more about it. So I was hoping in some help from the experts in the forum.

Hi,
it is with an immense pleasure that I announce that the gun project moves forward: I completed the main sight and scratchbuilt all the components of what i call the "superstructure" (the gun sight complex). Now it's time to bring them all together. Building the main sight was a gigantic (?or should i say liliputian  ;D ) effort that almost drove me insane and nearly forced me to abandon the project. My research (Dougie's input was providential, am very grateful) showed that U48 sported the gun version with no bolted joints for the deflection setting dial arm (b/w pic). This is what i managed to get, I hope you like it:
