Thanks for the info everyone.
Just read Ron’s guide and I believe they are both short frames. But just wanted to confirm.
Here are some pictures of the American Eagle.

What I need to know:
Will the cannon off this gun fit on a 1914 erfurt artillery frame and not overhang?
I know the sear bar is different but I believe these parts can be swapped?
Also will the hold open operate?

Also I plan to mount a 4 inch 9mm P08 barrel to this receiver.

I should note, all of these mods will be made by a very competent Luger smith, I am just getting the parts together for a build.
