It certainly looks like a step plate though I can only guess it fits a early COE but I havent seen 1 to compare.

@anthony-williamson Tony, Thanks for the reply....but I am familiar with COE trucks from 1939 through 1954 and this piece does not match up to the steps on any of them. Truck boards are all metal and sep plates are not usually seen on them. Yes, I know that there was a rectangular accessory step plate for AD trucks.

I could be way off base but it looks home made to me. The casting is a poorer quality that I would expect to see on a factory part or accessory.
