Check out the great instruction manual/user handbook for the "Vintair". http://www.salvimar.com/downloads/Vintair instruction.pdf
All the necessary information such as a parts list and exploded diagram illustrating all the internal components are shown. Seac-Sub produce a similar set of instructions for their pneumatic guns, but in recent years Mares has not. Yet in the early days Mares provided all this info, as did Nemrod.
