Found this rifle today at a pawn shop. The asking price is steep at $900, but I am willing to pay if it is worth it. The question is, what info do I need to gather to determine the value? Here is what I do know... The stock has a small compass in the top of the butt. (About as big around as a Bic pen) and the rotary mag has a counter. It has a side mount scope and a leather sling (which I know do not help identification. The rifling looks clean and sharp, and the gun has a nice patina, but it otherwise in beautiful condition. I will get the serial number and model letter ASAP so that I I can determine a value to offer for the gun.

Any other info that I need to know? Pros and cons? Strengths or weaknesses? Thanks in advance for any input.
