Do you know where I can find some history/value for my gun?

Question
Hi Paul.  I inherited a gun from my Dad. It is a Winchester Model 12 12 gauge full.  Speed and super - x 3 in. Shotgun.  I do have the serial number also.  Any idea where I might start my look for it's age and current value?
Thanks.

Hi,

Its value depends on it age and condition.
Model 12s are collectable. Any used gun dealer can give you its value.
If its a reasonable shooter they start at  $350 and go up.
