Yes it’s very different indeed !
Many years ago my late friend Martin Cooper started making this rather unusual beast but for some reason abandoned it. I came across the ‘action’ 6 years ago after he died and his sister asked me to have a look at all his airgun stuff.
He was a very clever and skilled engineer, a coded welded and had a good understanding of air guns and pressure vessels. He made to the best of my knowledge three precharged airguns, two as 0.177 target rifles and one 0.22 as a hunting gun, along with a very nice target pistol.
All of them are very accurate and well made. I own the last target rifle he made which he gave me six months before his death ( and flatly refused to take any money for it, having also given me his original target rifle 2 years before. ) I also own the pistol, which I bought from his sister after he died.
I gave one of my mates the early target rifle and another mate also has his 0.22 hunting rifle.
Anyway, the 0.25 beast was incomplete with a wooden front grip as the only wooden bit. I think he may have given up on it as it had a tiny leak in the pipe that went from the screw fitting made to take a bsa 200cc bottle.
The action has a VERY homemade look about it but knowing his pedigree I was happy to tinker with it. I’ve added a bestfittings quick fill so I don’t have to remove the bottle to fill it and also made a new transfer port system which Martin had made to, Ahem, be either 11ftlbs or 18 .
It’s now got a new single port and is running at 11.5ftlbs. I think the barrel is probably a BSA one as that was what he told me he favoured as they were easy to get hold of ( then ) and accurate.
One of our club members when he saw it said it was so ugly that he loved it ( and both he and his wife compete in HFT/FT comps so they know their guns )
It’s quite accurate out to 35 yards which was quite a pleasant surprise. I’ll try a post some pictures later.
