Parashooter: thanks for your comments. The auction ad does indeed say "NRA OR Bannerman," so he's unclear as well about the origin of his. Seeing the pictures provided in his ad, what's your opinion of the quality of this "conversion?"

For now I'm withholding judgment until I can at least access other authoritative works mentioning the BA Krags, e.g., Mallory, Poyer, and maybe try to track down pics, if they exist, of what a genuine BA carbine looks/looked like. It was mentioned the Brophy book had a pic of one, maybe there are others too.

Guess I'll be spending more money ...
