This is just a labor of love probably never used as intended. I'll just make a new piston. How do you remove this valve? Looks like it screwed in but I don't see any way to remove it?Ii has broken its spine in two, you can see where the metal has fractured. Not sure how that happened, dry firing the gun in the air maybe, but that piston has had it. Maybe salvage the piston tail and the rubber seals and use the rest as a sample if you can find a spare piston to compare it with. The Clipper was made up until the end of Nemrod's production, so finding a piston may be possible. Spain is the place to look as the guns were made there. From time to time Clipper guns come up on eBay, so you may be able to buy a gun for parts. Unfortunately the pistons are the first things to go.
I have the screw plug part. I had already removed it the brass washer and valve were stuck I had to drive it out with a pin punch from the back. Normally it should come out with the screw plug under spring pressure of the air valve.Here is the exploded parts diagram for the "Clipper".

Looks like something is missing in your photo. In the rear of the gun is a threaded bush with a screwdriver slot running across it that the sealing washer for the pump connection sits on. Under that is what you can now see now, so the bush that fits those screw threads is not there. The screw driver slot allows the bush to be removed, but whoever owned this gun has not replaced it.
Thanks, I've read some of the manual recently and these came pressurized with X amount of pressure and suggests you pump it up more for more distance up 200 pumps, no thanks! What spear gun would you buy today pneumatic or not??Rubber parts can stick as they age and deteriorate, normally they should fall out. The Nemrod rubber valve seals are a flattened ring that is not easy to substitute, as “O” rings don’t have the correct cross-section. A new valve can be made if you have the equipment to make new parts. Also by now Nemrod hand pump seals would also have deteriorated, but they can be re-equipped with custom made parts. Whether it is worth the trouble fixing these guns is questionable as much better guns are available. In fact the arrival of the floating after the shot Sten in 1967 basically spelled the end of the Classic layout gun with a mid-handle and a rear tank after about 10 years.
Depends on what you want to shoot and where.Thanks, I've read some of the manual recently and these came pressurized with X amount of pressure and suggests you pump it up more for more distance up 200 pumps, no thanks! What spear gun would you buy today pneumatic or not??
