Sorry if this is redundant. I'm a newbie. My father has recently become very ill, and I am selling off his gun collection. One of the firearms i'm responsible for selling is a full-auto British Sten. As far as I know all his paperwork is correct for this gun. he bought it about 15 or more years ago, and i remember him going through a long legal process with a lot of paperwork to make this purchase. My question, is what is involved in making a legal transfer or sale of this weapon? Can I even sell it for him? Or do I need him to transfer it to me somehow so that I can sell it? Thank you.
