ive got a fox DB .410 model E manufactured in mass. instead of PA.. i m sure that itis from the early 50's. It is in fair condition, still really tight, blueing is ok, but i've had it in my gun safe for over 30 years and i havent done anything to it. shows that it truely was well made as preident rosevelt stated to A.H. Fox. was wondering if anyone had any idea what the value would be just in fair condition?
