Thank you vonbulowfla,
I like this picture very much ,good reference material,studied this pic
for hours and hours,and I do have many things to do,and I have a million questions regarding this pic.But first things first.
Picture with the markings
Last week I noticed something that these ''H''shape plates do not have all the same size,
mmmmmm I think I am gonna used that on my boat,I have never seen this before on a XXI.
These floodholes of the XXI are very similair like the floodholes of the type`s IX,
here you see a picture of U-873 a type IX-D2,I was wondering if the type XXI has also this hatch,mmmmmmm this is a very intresting detail.
And here are some pictures of my work on the floodholes,
Well I must say it is a lot of work,but well worth,I think it is a fair presentation.
yes childeren now I am getting happy.
my best regards,
Ron.
