Yea, you're right. I forgot about the overhaul in 1923.

I'd still bet the barrels are older than the gun by a decade or so. You wouldn't have believed the projects in the rack at Bruchet the last time I was there. I passed on a Darne model C with damascus barrels that was waiting for a clean-up and a new owner.

Lots of trading of things back and forth between makers, too.

Best,
Ted
