I have a Wagner double skillet with patent numbers on bottom. Would this make it older than same piece with part numbers on it
 
yes it is marked 1402 first pic is of my bottom skillet. it has both sets of #'s. second pic is of a skillet on ebay it only has the 1402 # on it . they both are same skillet in every detail except numbers. would the patent # 's make mine the older skillet

The two patent numbers were from 1925 (Griswold) and 1935 (Wagner) as I posted on another of your FB posts. I don't know, with such widely spaced dates on the patents and two companies being involved how the marking with the patents and dating would work. One would probably also have to know the date ranges that the 1402 was made. If it came out before 1935 I don't think the patent number(s) would be on the pans. And when at least one of the patents expired (7 years back then??) would Wagner remove both patents? Did Wagner and Griswold have some kind of agreement to use each others' patents? The same patents are on the Griswold double skillets, at least the No.90.
