~Winchester Model 37 Steelbilt 12 gauge full choke~

My grandfather gave me his old Winchester Model 37 Steelbilt 12 gauge; no serial number. I was wondering if there is a way to find out what year it was made and what it's value is? (estimate for H.O. insurance purposes) He took great care of it and it is in excellent condition - no rust and shoots straight.

Thanks in advance!

No real way to tell when it was made. Value is $100.00 if fair, up to $300.00 is excellent. As long as the butt plate is original and unbroken.

these are very good guns.i've looked all over the place tring to find a 12,16,and 20,i got the 410,
most guys tell you the book price but dont go by
that.these guns are starting to be worth some money,
guys that are in there 60s i meet at turkey shoots
tell me mine is worth 1000 to the right person,and i
have herd up to 5000 for a set,so hang on to it and
dont be fooled by later models that are A models.
