Back in September, 2017, 'HeyJoe' made a Post, involving his possible School Rifle, serial # 342910.

His 'short rifle' was a bit of an enigma.

Some things looked good: a real model 1899 carbine barrel and action - (9 stamped over 8 variation), a credible stock with a second faint cartouche, barrel stepped for Krag bayonet.

Some things were odd: The front barrel-band fit to wood was a bit suspicious, rear-sight was a rare model 1898 'three-notch' carbine-sight and receiver serial number not in range for 1898 sight, and sight screw and front blade were poor replacements.

In view of 'Whig's' short rifle being considered a possible Philippine Constabulary rifle, maybe, HeyJoe's short rifle deserves closer scrutiny?

I like the report Joe Farmer gave Whig and his logic.  Sending for his book.  On my rifle the plug in the fore end was added by me as the original was missing.  Following advice the rear sight screw has been replaced and the front blade is now correct.  Shoots well.
