Parts for crosman 130

HI all, I just picked up a model 130 pistol, .22 call, version 1 at a garage sale today and it's missing the hammer spring and valve stem. The gun is in excellent shape, 100% bluing, no nicks, or rust in the original box with paperwork. There is also a partial tin of crosman pellets in the box. I think this pistol might be worth spending a few bucks fixing up. Anyone know a source for parts or possibly want to buy or trade for air gun stuff?
