    You could check here http://www.pyramydair.com/manuals and find a Beeman model that looks and acts like yours. If it's a pneumatic, pump up, just oil the mechanical linkage until you read about it.

    Wow,thats an old one!! I believe those are Diana Model-6 that Beeman imported several decades ago under their name as the 850,which is the recoilless version of this pistol. Its a spring-piston(springer) so the same basics as any spring-piston gun should apply.

    It probably needs to be completely stripped down,piston inspected,old grease and oils removed,new breach seal and piston material replaced(if synthetic),re-lubed with correct lubes for spring guns.

    If you go to do it yourself you need some kind of a spring compressor to ease out the mainspring. Correct lubes/parts can be had from James Maccari.
