Ole Butch used to call them jam masters. I never saw it that way. If you took them out of the stock turned them upside down and gave them a bath in kerosine then blew them out with a compressor they would run with any 22 auto on the market. They have been making them for so long that when you buy a used one it has a good chance of never ever having been cleaned and has a bunch of rounds put through it.
My good friend Ray no longer has his gun shop open to the public but he still takes care of his loyal customers. He sells his trade ins on gunbroker. Last night I was out at Rays shop and there on his rack of used stuff were 2 GLelnfield 60s. One was the old "Squirrel" model with the squirrel engraved into the pistol grip. It also wore a same vintage Weaver B4 4x scope. That package was as clean as your going to find one of those old rifles. The other was one of the last run JM guns. It has an 18 inch barrel and no scope and from looking at the tip off groove it's never had rings mounted.
I gave Ray $225 and took both of them home with me. While watching my Vikings play last night I took the "Squirrel" gun apart to clean and it was obvious that it hadn't had a 100 rounds through it in it's lifetime. There are only a few tiny scratches on the forearm. I am as tickled pink as if I had struck gold and over a gun that didn't cost $50 when it was new. Silly old fart anyway.
The other 60 is just as clean. I put a sling and a 1 inch tube Bushnell 3x9x32 rimfire scope on that little carbine and it will hang on the wall at my hunting cabin.
It seems that in my old age just simple stuff that takes me back to my roots tickles my fancy better than the expensive new fangled stuff that cost way more.
