    Old?unusual multi pump rifle U.S.A. opinion please

    As above really. Nudged by another thread decided to get this one apart to see if we can get it working.
    Marked J C Higgins "22" Caliber 12619300
    Sears, Roebuck & Co Made in USA Also 992529 on breech cover.

    Think we know how it works and seems to be intact but weary in parts. A non return? valve inside the compression tube. Don't want to disturb it at the mo'
    Asking them that know. Is anything missing? What's operation sequence please?
    Thanks for looking.

    It's an early Crosman 140, Jules :-

    https://support.crosman.com/hc/en-us...0/C140-EVP.pdf

    It looks all there, the valve seal kit for a Crosman 1300 pistol will fit it.

    Operating sequence is pump it up, put a pellet in and fire --- the exhaust valve self resets if it's working as it should do.

    I agree with the above, very similar to the Crosman I had many years ago.

    Some obvious differences:

    My old Crosman had a clip-on rear sight (hopelessly inaccurate).

    It also had an alloy pressure chamber, and there was no transverse screw above the trigger, but it did have a safety catch.

    DT Fletcher can give you the exact details, but that was a modified 140 made for Sears (“JC Higgins” brand) in the - roughly - late 1950s through 1960s.

    As per my "wanted project guns" ad, if you get stuck I'm always looking for interesting challenges
    Always looking for any cheap, interesting, knackered "project" guns. Thanks, JB.

    Thanks for great responses. T20 I will chase the seal kit tip. Thanks.
    I get pump, load, fire, sequence
    Guessing the trigger holds the valve cap shut, against stored pressure, via push rod etc
    After firing the spring closes valve again?

    Hi Jules.

    The inlet valve is the same as still used in the Crosman 1322/1377 but I normally lap these back in if needed --- a saw cut across the back face allows you to use a screwdriver.

    The exhaust valve inner seal is an imperial Quad seal, I normally dig these out and fit a metric O ring of the appropriate size.

    All the other seals on the valve are commonly available Imperial sizes which you normally find in an automotive selection box.



    Yes, the trigger holds the exhaust valve closed onto the end of the main brass valve body, on firing the exhaust valve moves backwards to open, then when the pressure has dropped the spring returns the exhaust valve to the closed position.




    All the best Mick

    Ah, What you're taking for a screw above the trigger is actually the safety catch on an early 140 --- later 140s had the safety in front of the trigger.

    Thank you for that, so it seems I had a later 140 then, a mate had the same rifle, but with a very plain stock, darker and no cheek rest like mine, this would be in the late 60's.

    your better fitting the quad seal as opposed to fitting a std o ring
    if you want a seal kit I keep them for these but don't do an original piston seal for them ,but i do an o ring conversions and all my 140's have blow off piston to stop them going above 7-8 fpe
    the barrel is the same as the 1400 and some of the sears 1400's had scope rails cut into the barrel
    the white spacer was only on the catalogue guns afaik
    the early inlet valves were ally and had an o ring to seal instead of the ptfe ones and with the trigger in the stock models you had to ensure the stock screw was tight or they would fire whilst you were pumping,reason they went onto the cast trigger unit on the 4th model but the triggers on these wear and allow the sear block to go back and again fire whilst pumping

    Thanks again all. Great info. on seals etc
    Ped there is a synthetic seal on the non return valve. Looks tapered? Maybe deformed by age.

    Also see Crosman 130 for details of the check valve seal.
