That may be a serial number, which MIGHT help establish a date of manufacture IF we knew the exact manufacturer and model. It was most likely made sometime between 1930 and the mid 1960's and I would suspect it is a Savage/Stevens product. I'm assuming that it is a field grade hammerless boxlock, and if this is right, its value will be determined by its condition. Top dollar would be around $300 in like-new condition, $200 +/- in "average used", or less than $50 for a broken/rusted/worn-out parts gun.
i need price and value on a 20ga Montgomery ward and company western field browning modle30
Anonymous - I think I've located the correct cross-reference for this. If it is a slide-action shotgun, it should be a re-branded Savage/Stevens 520 worth $150 in excellent (like new) condition or $25 if just a parts gun.
