I don't remember what model it was, but I'd know it if I saw one.
It was a break barrel springer. Pellets could be loaded while the barrel was open. It also had a BB magazine inside the receiver that would dispense one magnetically if I pointed the gun down correctly.
Pretty sure it was a Daisy - I kind of remember it coming with a tin of wadcutter pellets, but I don't know if that was in the package deal or if it was a stocking stuffer. Man, those things were like GOLD to me, as I didn't have money to buy more (my money was always saved for buying Comet model airplanes). The plastic stock was brown. This would have been the early 70s.
That thing is why I never want another springer or break barrel. I envied my big brother for his Daisy 25.
