Welcome to the forum! I agree with others that this is, if not THE best gun forum, it is among the best. Good, actual gun slinger moderators with a passion and history in firearms, and for the most part, great members. I don't think your question was dumb at all. While I have never bought a used firearm, many used guns are sold without manuals. And sometimes the owners manual is not available on line. Sometimes it is. My inherited weapons, like my click clack savage, info is hard to find. A question asked in open forum can spark an idea or a clue for others experiencing similiar problems.
Again welcome!
