thanks for your information...hopefully I can narrow that down but I appreciate your response...1 7/8" is what I measured...
I had read that mine might be a "roving/floating J" serial from 1970/71/72 so your information lines right up with that...thanks
is there a way to know if mine is a factory nickel Model 36?...someone told me if it has an "N" marked somewhere but I have not seen that anywhere...further, many photos I have seen of factory nickel show a color case hardened hammer and trigger whereas mine has nickel'd hammer and trigger...
