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!
