Quite possibly although I might mention that a few years ago, I reused my 45 again, after a period of non use of some 15yrs and it worked as though it was new.
Since I bought the 45, the pellet choice has widened considerably. In 1980, I discovered that Silver Jet pellets were best. They have ceased production but there are plenty of other new pellets, just as good. Personally, I cannot speak highly enough of the 45, even although the triggers were not as good alongside today's equivalents. That said, everything else was superb.

i managed to pick up a mint diana 75 last week from a fellow club member for £350. I agree that people are tending to hang on to them now, which is driving up the price.
