Hi all. First of all, I'd like to extend my appreciation for all the information on this site. I've been able to find pretty much anything I need regarding cast iron here. I'm a long time reader but a first time poster.
I haven't been able to find an answer regarding a recent purchase. Very simply, what does the "A" mean after 9 at the bottom of this Wagner? I know letters and numbers like this generally designate foundries, molders, etc. But has anyone been able to decipher this any further? Thanks for any assistance or suggestions.
