Hi Dougie
Maciek - very interesting on the grid for the cooling water system. I think it is also there on photos of U 47 and U 54 but not close enough to determine any detail. Perhaps you may have seen the grill on other boats.
I will look from my set of the photos.
I wonder if I may ask a few questions about it -
Was the grill in the exact same location as the opening on U 995?
Well, U 995 as the type VIIC boat was slightly longer than type VIIB. But I think that if you
would like to locate it by measuring distance from the stern, it would be the same location.
And was the grill square or rectangular?
Well, I would say the grill was circle shaped.
Lastly, any ideas when the grill was discontinued in favour of the hole we see on U 995?
What we can see on U 995 is not original state. On stb side we can see the hole, port side hole
is blanked. I think, that when U 995 was in service, the holes were covered by grills.
