Your question is a little vague, so here is my suggestion. Go to a book store or library and look up a book called "Blue Book of Airguns 8th edition" Two different companies made a Plainsman air gun. First look up "Challenger" (They sold Plainsmen) then look up "Healthways" who also made several plainsmen models. From here you will be able to identify your model and get more information.
