Griddle ID help

I found this griddle at an antique store and got it for $8. After some lye and then vinegar it cleaned up pretty well, although it is slightly warped. The only mark on it is "8a". I haven't been able to identify it. The handles look similar to Wagners but I haven't found any that match it. I also found an expired ebay post with an very similar griddle suggesting it is an unmarked Lodge.

Any thoughts? Thanks a bunch for the help.

Although later ones (or other sizes maybe) did not have the reinforcement ridges, the handles are a match for Lodge, as is the number style and placement. The raised molder's mark would place it 1930s to maybe 1940s.

Thanks a bunch Doug!
