isabelladangelo, you may be right. It wasn't an air gun - it was a spring gun. You cocked it like a Winchester, as you see, but what you were doing was more akin to cocking a crossbow - a powerful spring was forced back to catch. Released, it propelled the BB.It worked well enough for target shooting.
By the way, thudpucker, I think you're wrong. #10 is, as I said, a BB gun - suitable for small fry - but the two older kids are holding .22s. See the ejection port on the right side of #3's receiver? That's a real Winchester design - the lower 'barrel' is actually a tubular magazine.Bobby Brylcreem, there at #1, has a single-shot weapon - though of much higher power and accuracy.
