Questions about a two wheel trailer

[wingrider 21]

I have a two wheel dump trailer that I'm trying to identify its origin, it looks a lot like the ones i've seen on this site. It has a dump body that looks similar to a wheel borrow on a trailer frame but backwards. Are there any numbers on these trailers that would say if its Wheel Horse. Any help would be appreciated.

Thanks Gary B

Most have (or used to have) at least a serial number tag. After about 1965 they all came with the standard black and silver stamped aluminum tag. A picture would be most helpful. Post one of yours if you can, otherwise please take a few minutes to look around the implement gallery and see if you can find one that looks like it and let us know. There were a few different shapes and sizes.
