Traditional Rifle unusual air rifle 100 shipped to lower 48

[Slingworks]

i bought on a whim at a show. thought at first to give to my son, but after thinking a bit not really his thing.

100 shipped to lower 48

this is an apache made in the 40s or 50s. i think is a 22 cal.

it does make/hold a little air but probably could use some attention to make it perform properly. maybe new or greased seals? sold as is, i know nothing about it otherwise
