Very unusual Norden Bombsight

[tenacious101010]

In need of some Norden Bombsight information. I have found a bombsight that I believe is a Carl Norden designed bombsight. I also believe it is a very old one and am trying to find out if there are any out there older than this one. Are there any bombsight collectors out there? Looks like I need to learn how to load images now. The first image is the mopre common Norden bombsight. The next few are of the one I found.
Thanks for your help in advance!

Thanks for the help Chris!

The only way to tell at this point will be to figure out the serial number. If you wouldn't mind please post photos of the numbers stamped on the internal parts throughout the sight and please post them. I would love to see any good detail shots of your M1.
