     Looking for some info. I picked up this old Crosman powermaster 760 from a flee market for  $7. Won’t pressure at all, took it apart, appears the piston cup was torn. I’m wondering if anyone can identify the variant of the rifle.  Serial number 05825197

    According to your serial # it was made in May 1982

    That’ why I’m here.. according to https://www.crosman.com/discover/crosman/crosman-product-dates, the 1982 model had plastic bolt.. mine is brass

    Also, in looking a replacement parts, this appears to have “old style ” valve, and piston cup 

    this model also predates the mechanism with trigger  to prevent firing with bolt open..

    It’s possible a previous owner put in parts from another gun that was used for spare parts

    Turns out it is a third variant.  Judging by the breakdowns found here: https://drive.google.com/file/d/0B2hkfoL4OoEfSC1VMVFWeUpTa1U/view

    Matches the pre 1975 models
    Taking closer look at the gun compared to the crosman site, forend is definitely wood.

    Yeah, variant 3, since it has the same valve as my variant 1 built 6/70;

    I am in the process of rebuilding a 760

    Not sure of age but it has plastic stock, plastic forearm, plastic bolt with brass lever 

    The valve assembly is  brass and pointed.

    It built up no pressure, everything was nasty gritty . I'm thinking a new piston cup, replacement valve, lost of grease and sanding, painting and smoothing.

    Got a pic of it? Sounds like a Pumpmaster?
