your Western field model 60 shotgun was made by Savage arms for Montgomery Wards(western Field).The Savage model 620A and your shotgun are one and the same.If you go to Savage arms home page,they may be able to say when the model 620A shotgun was produced.
Most used Western Field pump guns will bring $100-$250 depending on condition and model/style.

10-125 USD or so
I think your shotgun was made for Montgomery Ward by Savage as their Model 620A. SOME parts are available from Numrich. These were made starting in the mid 50's, and are about $150, depending on condition.
