CarlMuss your work is incredible.
I was very impressed by that 314 nameplate shown earlier in the post but it may not be real.
This is an ebay auction from an boeing exec that had a lithograph and commerative piece of the 314. As you can see in one of the photos, there was a duplicate plate made for each one. This piece is missing it's duplicate plate, but you can see the area where it would have been, it looks like it was ripped off the paper.
