Does anyone know why there are 2 holes drilled on the left side of the barrel on this 1903 model 22 ? I am guessing they are for a scope mount of some kind but which kind? Someone has filled the holes with solder in the past. This is a rough ole gun made in 1911 but shoots very well. Thanks

Almost certainly for a scope mount and likely for a Weaver mount since I think I can see where the forend has been relieved a little along the barrel channel also. What is the CtC hole spacing?

Thanks! The spacing is 2 3/8″ between centers.

I have one of those Weaver barrel side mounts (with the scope) somewhere in my parts bin. I took it off a 3rd variation Winder Musket about 20-years ago.

Hi Cliff,
The 2 center mounting holes on the Weaver N2 base are exactly 2 3/8″ CtC. That was the most commonly used .22 rim fire base with that hole spacing, although there may be others.
Hope that helps.
Best Regards,
