Not sure about the thread ... can probably make anything work. Should be about 2.5cm (~1") across

Your gunsmith can likely make a cerrosafe cast to identify the thread.

Good idea Mike!

Here's another even cheaper idea...

If you have (or have neighbors with...) little kids or grandkids, carefully screw a 1" or longer piece of a broken crayon in, and then carefully remove it and measure. The wax is soft enough to engage with and be cut by the real threads, and if any remains in afterwards -- a blowdryer, a dental pick and Q-tips gets it all out. One time, I had to reduce the diameter of the crayon slightly first -- you can taper it so it enters more easily. You can get the pitch (threads per inch) off partially formed threads, but you'll want at least one or two full threads to get the true diameter; and that's where tapering the crayon helps out.

Yawohl, it's a hokey home gunsmithing trick -- but it's worked for me.
