Crosman 1377 advice

[T 20]

Thanks Mick, serial number is 478003115, hope you know how to decipher it!

Made in April 1978 --- it really needs buying and restoring.

Okay, I am getting more interested...
Would the 1399 stock fit or is there a more suitable option for the vintage. Also, does the price look OK, or should I try a cheeky offer?

Yes, the 1399 stock will fit, the one I bought new in January 1979 came with a 1399, the only alternative to the 1399 is the very rare wooden stock.

I'd try a cheeky bid of £60 --- it would be rude not to.




All the best Mick

What does the wooden stock look like?
There are lots of after market versions available, but I have scoured the Web for an image, but to no avail...

If it isn't too complex, and assuming I am successful in the purchase, I might have a go at whittling one.

Cheers,

Mark.

Well the phase one 1377 is now mine, it has seen a bit of action, but does work, sort of...
It has apparently had new seals due to the valve leaking, it now holds air, but for some reason, it isn't very good at lobbing the lead very quickly, even after ten pumps.
Suggestions on where to look first would be welcome!
The other things of note are that the barrel is the original one, and the grip once had the crinkle finish paint, but now it is stripped back to base metal, apart from the last bit inside the trigger guard.
And to think, I could have had a brand new one for £95, but where would the fun be in that!

check to see if it has a blowby valve or stem fitted also check that the non return valve is sealing properly
other things are worn cup seal or the seals were badly fitted and air is leaking past the valve
could also be leaking at tp or probe seal

[Modski66]

All the internals and seals seem okay, apart from a lot of oil slathered everywhere and the graunciest trigger I have ever used...
But the thing I don't know is if the piston seal that looks okay to me, is actually letting by on compression. Is there anything I should be looking for on the edge of the cup?
