I don't know if you forgot about me or couldn't find anything on my old .22 (from orginal thread). I have searched all the books I have and couldn't find anything on it. The info on it
HAMILTON RIFLE NO. 51
22 CAL S - L & LR
C. J. HAMILTOM & SON
PLYMOUTH MICH. U.S.A.
If I remember correctly this rifle has been around the house for at least 35 years and I think it was an old rifle even then.
Thanks for all the effort and assistance
