None of the dimensions nor photos match with anything in de Haas' drawings.

Curious minds and all....

Thanks!

that round was popular in single shot actions, with that extractor cut could it be from a single shot?

A pivoting extractor a la' Stevens.

thread diameter is too small, thankfully, 'cause I don't want to imagine someone converting an original Sharps back in the day... then again, the Sharps Borchart used smaller threads, I think.

The first few pages look to be copies from the de Haas book.

extractor. Made me go check both of mine and that angled cut is definitely there - extractor clearance as it runs up and out the top of the action. Appears the Borchardt's extractor is at the 3 o'clock position and it doesn't have the lever like the 1874.

Checked my 1885 and it is at 6 o'clock and no angle cut that I can see. Never had one off to know for sure. Browning 1885s are supposed to be .935"x20tpi. Whatever that is, it is coarser than 20tpi. Would help if we knew how that extractor cut indexed relative to the rear sight dovetail.

I wonder if that barrrel originally came off something else; those V threads shouldn't have such flat tops unless it was "made to fit" something else.

The .25 Krag sure got my attention. A bit of surfing shows it was a pretty hot number in its' day (and ain't too shabby today neither).

Thanks for your observations John.
