Diana Model-60 - Hy-Score.
With thanks to Mike D for these pics of this amazingly well-preserved Hy-Score branded model 60, about which he says:
"It's well-known that this was the first truly recoilless spring-piston rifle to hit the market, in January 1963, beating the FWB 150 to the market by several months. This example dates from 1967.
I have always been mystified why the Diana barrel-cockers were not more successful in competition. The workmanship and finish are top-notch, especially on early model 60's like this one. The trigger and sights are very fine, the gun is utterly recoil-free--more like shooting a pneumatic than a springer--and in their day they were even quite a bit less expensive than the recoiling Walthers. I can only assume that Diana was not too good at the advertising game!
If the 60 has a mechanical weakness, it is the ball-bearing breech detent inherited from the little models 25 and 27 sporters. This can create vertical stringing problems--especially with the heavy barrel sleeve in place--if the breech is not carefully lubed and correctly tensioned.
This gun has a bit of a story--it was never sold at retail before being found in a Pennsylvania gunshop (mysteriously, sans rear sight) when the owner retired. I just missed it when it was first sold, then picked it up a year later from that first "real" owner. In the meantime, he'd had it rebuilt by RWS...how's that for dumb luck? It's about as close to a new model 60 as it's possible to get, and came with the original box, paperwork, sight inserts, and universal tool."

Thanks to Mike D again for these pics of his August, 1982, Diana mod 60 with rare tyrolean stock.
Note that the presence of two trigger blades does not mean this rifle has a double set trigger. Rather, the forward trigger is an optional screw-in extension designed solely to lengthen the trigger pull!
