I just got my hands on a Model 36 with pinned barrel and flat latch serial number 386xxx. Trying to find out what year it was produce. It is nickle and what style of grips was on it orginally. It had after market herrettes on it.
Welcome! It is from about 1964, and would have had Magna or service stocks, checkered and with uncheckered diamonds around the stock screw. Hope this is helpful.
