One day, I found a Diana model 24 of the same vintage as the Webley Airhawks, and since WebLey Airhawks are really scarce here in Norway, and it was really cheap, I had to buy it. I didn't collect Dianas, but that old D24 got the ball rolling....

And now I wonder, how fast are my Diana 25's really supposed to shoot? Google has not been any help, theres only posts and videos of .22's.

The german one has a worn spring and is putting out 490fps with 7.33grs JSB's, that might not be their full potential? Is 550 doable with a fresh spring?
