A co-worker has announced that his elderly uncle can no longer hunt and would like to turn a couple of his guns into cash. I am interested in the 300WinMag that he has, but once the co-worker brought it to me to look over, or test fire if I care to, I am a bit nervous. It appears to me to be fairly old, and I cannot find any manufacturer name or serial number on it. I raised my concern to the co-worker and he advised that his brother has a gun that does not have any markings on it because it was tailor built by a gunsmith to his exact specifications, what with him being a larger man and typical guns did not fit his frame so well. He says the brother spent over $1000 having the gun built. But I digress, he would like $350 for the gun, I have a couple pictures I will attach to this, and await your wealth of knowledge and advice. I am, as he says, "just a pup," and that in the good old days, there were more gunsmiths and it used to be more common to have guns built. I am skeptical and affraid that it is a Frakenstein that was made from spare parts. Thanks in advance.
