Hoping you good folks here can help me establish a realistic price on a Ruger revolver. Want to buy it from a relatives estate, afraid they are asking too little & want to make sure I pay them what it is truly worth. Revolver is a RB22 - 6 1/2" Bisley single six, drift adjustable rear sight, patridge front & fluted cylinder. No box, gun shows no wear - is in excellent condition. Included (I think it will be included?) is a Ruger/Bianchi flap holster still in the plastic bag. Serial number dates it to somewhere late 1985, early 1986 if I'm reading it correctly. Thanks in advance, again, want a real price that will allow me to be fair to the heirs.
