Now sorted regarding the grip, as usual a chance question and one popped up!
(in return I had to drill and tap a Paratrooper frame to accept the longer grip / combined forend style bit of kit the owner was replacing the single grip with).
BUT......The thing was not latching, so when eventually apart and the long tray examined which contains a collection of parts which look like gun parts, but made by a 10 year old, I could see nothing obvious, the sear swings and latches, and the trigger releases it, but it (despite a good clean) is as gritty as hell, and if the whole shebang was not riveted (well pins bashed by a maniac would be more accurate) together, I would smooth a few edges out.
So is it a trigger adjustment issue ???, I did play before I stripped the trigger mech out, and it would latch but not fire. The parts seem very little worn, and the piston cutout seems in good order (cylinder and barrel assy still complete), ie. no obvious cracks or burrs which I expected from the feel of it.
Any ideas, links to remedies would be gratefully accepted
If you are a Paratrooper fan (I loved shooting them in the 70's!) then sorry for the above description, but after working on and German stuff, this is pretty dire in quality regarding the inner workings
