Hah ! I just found the same thing, an osprey with the barrel snapped off. This is a hugely interesting & useful thread to help me to put the osprey back into a useable condition & perhaps mod it a little ,Love the idea of a leather piston seal. the stock on my find is lovely, but alas only Beech ! I got this along with a sawn off Hungarian break barrel springer, I'm guessing a Relum ? ( L.G.....Lampa Gyar )...Lamp Factory .& a complete but bit rusty Diana 25 with a bent barrel & the sear doesn't want to engage. Price..A score for all 3 !, gotta love North Wales flea markets !
