    Model 12

    How do you determine the number of 'pins' on a model 12? What am I looking for.
    I have a pre- 64 with a Simmons rib and a ws-1 barrel. Thanks

    John

    Just a little more info, the pins hold the rib onto the post from side to side.

    Only two varieties of Winchester ribs are "pin specific" ribs. They are the two pin, the original Model 12, 12 gauge vent rib from about 1917 to 1960 and the three pin, from about 1961 to end of production. Other ribs without pins were made from 1954 to about 1961.

    Absolutely makes a difference in price, and a correction to the no pins, all Y models ribs are held on with an Allen Screw in the rib at the Muzzle.

    The milled rib guns are made completely different, the rib is milled in one piece w/supports.

    The later models are ribs slid onto pins silver soldered to Bbl.

    You can easliy tell the difference.

    The spade on the reciever has milled grooves, the later models are smooth Spades.

    Here is a post with a picture of a 3-pin model 12. The rib is attached to the posts with 3 pins -
    the vent rib on a 2 pin model 12 is attached with 2 pins.

    Sorry about the omission of the Y gun. The Y gun is, of course, different, and worth less than any of them, assuming all are original from the factory.

    I have one from around 1960 that has one pin at the rear of the rib, rib also has round posts, it is not a Simmons. What would this one be called?

    Yup, and commonly referred to by collectors as the "round post vent rib". There are apparently two types of round post rib, solid and hollow, but identical in appearance.

    M-12's with Simmons rib do not carry the value of M12's with
    factory installed ribs.

    My M12 has the "Special Rib", as Winchester advertised it.

    I had a Skeet M12 with the same rib, just a few hundred numbers diff.

    Both guns were ser.# 1,795XXX.

    From what I can tell the special rib guns seem to run in the 1,700 range.
