I am looking at a Marlin Model 57 in .22 Magnum. It has a three digit serial number on it. 773 I believe. The stock is not varnished and there is no white spacer between wrist cap and stock. The rifle is in beautiful condition but the unvarnished stock bothers me. It is very smooth. Did they make these with stocks like this? He is asking $575.00 for it. Any info on this is really appreciated. Thanks.
