I got this rifle (the middle one) quite a while back. At the time I thought it was a Mod 23a. It sat in the safe and gradually worked its way to the back. I found it again the other day & now I’m not sure what it is.

Top Mod 19-1933 s/n 520xx
Middle Mod ?? s/n 215xx
Bottom Mod 19-1919 s/n 65xx

The barrel and receiver are one piece. It uses the same magazine, bolt and butt plate as the Mod 19-19. The barrel dimensions (diameter & length) are the same as a Mod 19-19. The stock is the same as the Mod 19-19 except it has been shortened, and looks factory done.

The shape of the oval ejection port is what’s confusing me. It’s the same as the 23a but if that was the case the barrel would be more tapered.(?) It also would have come with a different stock.(?)

I have heard there is a Mod 22 that was made for one year only, 1922. It was a transition rifle from the Mod 19-1919 to the Mod 23a. It used design features from both models. Any thoughts / info?

If any one has a 23a can you tell me the diameter of the barrel at the muzzle?
