I received a bunch of these several years back. This kit includes, an 8 inch brass barrel (plastic coated on outside) (ID is .685), a 12 gram quick changer (thread is 8x32 instead of 10x32 so that is a little annoying but the speed wheel is really neat), a steel front grip frame screw for a nelson 007 frame, a plastic body with metal thread insert and a metal spacer that goes between the valve body and the gun body. No internals, completely empty. Plastic on end of barrel does have some wear on plastic.
