I had one as a kid, it was pretty horrible to shoot. The lever was damn difficult to crank back towards the barrel to charge it and you had to remember the Kentucky Windage to get the BB on the target.

I plinked with it for several months and somehow got a parent/grandparent to fund a Crosman 776 multi-pump. That was a "real man's bb gun" (*smirk*) back in the late 70s.
