Air rachet/air chisel/air gun

I have a set used and all works well. The air gun forward and rev. pin acts up. These are not top quality but do work fine. Has chisels,sockets, 3/8 to 1/2 inch. adapter and all fittings on air tools. Has a case with it. Got new ones and iam asking $30 for all because of the air gun problem. Plus shipping and best offer. Thanks
