That's the one. I had no choice when I rescued this one from a small interior town in B.C. Came from a farm where the wife used it to pot deer. It needed about everything. SURPRISE, the bore is very nice and very tight. I wanted a Marlin that had a Ballard barrel and now this one and a 336A from 1948 as well. Price on this worn old piece was $500 shipped and a bunch of parts that members here helped me procure. Anyway, here it is. Yes, low number and no prefix. 1936.
