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.

Notice the 2 extra horizontal bars in the bow tie!  I don't think GM would have done that.  Plus I bet its white metal casting similar to matchbox diecast pieces.

Probably a Chevy enthusiast who made a conversation piece for their motorcycle.

Hi Junky

The 2 lines were used earlier on.  🙂

They were on the emblem on my '29 (like the attachment below), and still in use at least until 1954 (which is the last Chevrolet Service News issue that I have.

The proportions of the bowtie and the angle of it's ends do seem to be off though, so I would agree that it doesn't look quite right to genuine Chevrolet.

I have a very vague recollection, but didn’t Chevrolet experiment with producing farm equipment for a short period of time?  I am wondering if this could be a step plate from a tractor or similar piece of equipment?

It wasn't Chevrolet per se, but GM that bought the Samson outfit which made tractors.

They did this to compete with the Fordson.

GM ran the outfit from about 1917 to about 1923 and then gave up on the idea.

During that time, they apparently made and sold some trucks as well, which used Chevrolet engines.

So... your idea is certainly a possibility!
