Looks like a Crosman 2200 MAGNUM to me.
I can say with absolute confidence that it's not a break barrel. I see no pivot and it is a receiver/breech loader. The shape of the stock screams Crosman to me. The receiver says Crosman or even Daisy. The lack of the pump arm rules out Daisy. Got to admit... I'm baffled. I hope you sort it out and find one.
