I have a 1910 Model M/S made before WW1. It's a rifle w/about a 26" bbl.
The bbl has a full length rib on it. Looks to be original to the rifle from the markings on the bottom.
I haven't had it in the light of day recently.

The stock is now a 1/2 stock, but I believe it was a full stock from the faint line on either side of the bbl ahead of the wood indicating a wood line and indication of a muzzle cap.

The bbl is marked w/ H. Barrella (sp?) , Berlin ,,the retailer I assume.
A German (re)proof mark dated 1913 on the right side of the bbl just ahead of the rc'vr IIRC.

Scope mounts (claw) and 'scope no where to be found.

I bought it from an elderly gent who said his older brother brought it back from Europe after WW2.
That may explain the cut stock (duffle bag cut).

I was going to fill in the clawmount dovetail and rear mt holes, but have an '08 w/ scope and mounts that may give up it's optics for this one. The 1908 wasn't fitted up very well to begin with so I'd rather fix up the 1910 with them.
