I was just in a local gun shop and found a Marlin 336 .30-30 prior to the trigger/bolt safety (about 1980). No checkering. It has a scope base and seems to be in good condition. Few scratches in the stock, very superficial cosmetically. Action seemed smooth.

I'm by no means an expert on gun conditions. The shop is asking $250.00 and said it could come down since its a consignment gun. Seemed to really want to sell it.

1. Is $250 a reasonable price?
2. Other than looking at the surface how should one go about evaluating a use gun. (So I can try and sound like I now what I'm talking about)

Any help would be welcomed
