I picked up a Hawthorne Mod 130. It looks like a Crossman a Mod 130. Was it made for Wards? When I pump it, it sounds as though the air is leaking out from the barrel. Guess I have some bad seals. It will not build up pressure. Are the parts the same as the Crossman? It is a dead look a like to the Crossman Mod 130. Thanks for your time. Rog
