'Jwagar' - Welcome to the KCA Forum. It sounds like your Krag is a real interesting puzzle!

FWIW - It seems to me, your receiver, #16720, is unlikely to have been used by Springfield Armory on a model 1896 carbine.

Your Receiver was likely manufactured around June or July of 1895. (It is real strange to me that it is dated "1894")!

BTW - Manufacture of model 1896 carbines began late in 1895, at around serial number, 24709.

Your stock and hand-guard appear to be correct model 1896 carbine components. I don't recall ever seeing a Krag stock with two J.S.A. 19th century 'cartouche' stamps; that's a new one for me!

Please take and post some clear/close-up pictures of sights, muzzle crown, and markings.

Is your receiver 'notched' for the extractor 'hold-open pin'?
How many cleaning rod holes are in the stock's butt-trap?

I am delaying judgement. The facts you have stated create an enigma.
