most common by far and the only schanble tipped 99 made in 1949 (I am 99% on this but will allow an expert to tell you for sure)...it it is a 1949 there should be two letters followed by the letter A on the lever boss.
1949-A 1950-B 1951-C etc
Like I said though...the best thing to do is just post a picture...everyone loves looking at these old guns...
