Hi all,according to wikipedia..."Cooey model 84/840 shotguns that were manufactured BEFORE 1970 do not have serial numbers, the shotguns made BEFORE 1961 are stamped "H. W. Cooey Machine & Arms Company" on the right side of the action and the guns made after the purchase from Winchester of Cooey are stamped "Winchester-Western (Canada) Limited." on the right side of the receiver." My prob is that I have two Cooey 84's,a .410 and a 16 gauge,the 410 has H.W. Cooey machine and arms on the RIGHT side of the receiver and Cooey model 84 on the LEFT, my 16 has H.W. Cooey on the LEFT side of the receiver and Cooey 84 on the RIGHT,the markings are opposite,the really confusing thing is that they both have serial numbers on the right side of the receiver. s it safe to assume they weremade before 1961 and the numbers stamped later? Just curious,I found it a bit confusing.
