Daisy Model C02 200 Semi Auto Pistol( B.B)

As above title indicates. Unique design in that it has no seals, it does hold air(C02) though. Only issue is that it doesn't pull B.B. from reservoir into barrel to fire??? I can't figure it out(I'm not the original owner). I'm sure someone on here who is more familiar with these could figure it out. It does come with oringinal box and adapter for shorter cartridges although it takes the regular Crosman cartridges as well. Asking $45 shipped. Send me your email for pics.

Doug
