Thanks for the reply. I have added an image of the inside of the grips. The proofs are definitely E/135 on the receiver but the barrel is proofed with E/655 best I can determine, unless there was an E/855, which I didn't think there was. The s.n. is 4275a
I'm not sure that I should post images here, but hopefully someone will let me know if I do something that I shouldn't.
thanks again for you help, barr44
