You are welcome Jeff. Agree with the A-6...more than likely released after Cat. 45 was issued, that's why we used the words "about". The 1915 date would be the ending date, as I have an article that state Cat. 46 was available in 1915 (May). Hard to track some of these catalogs. I have some that run about 2 yrs (on the dates) in Bulletins, and others have three plus years of Bulletins with different dates.
The 15 in Aluminum, I am not sure of (don't know that they made that). I would have to go look at my catalogs. I know, for example, that even on the skillets, the slant/Erie 2, 3, 4, 13, 14 were released at different times. The 3 &4 were after Cat. 45, then the 2, etc...so some show in some years, but not all.
This is just to give an example of what kind of data WAGS has available on the membership side. Many members have given to our data base to make it what it is today. The largest, most complete data base on foundries available, anywhere. :)
