470-

Went back to the shop and got some more details for you.
I'm not sure what you'd want to hear, but right off the bat I'll tell you it's definitely a CZ and a Manchester gun -- that's roll engraved on the left side of the reciever. I was wrong about it being engraved with whitworth express on the barrel, it simply states in special font the chambering -- it's the red rubber recoil pad that reads Whitworth.

I have notes of the marks around the underbelly of the reciever and other areas under the wood line, just ask for what you'd want to hear...
