Help with a 1930's trailer

[Zetomagneto]

Gibson Eccles trailers look like this:

Thats the only other one I have ever seen, I have had total a slightly different design with mine as it has to earn its keep so I have made it deeper. And for safety it has proper Antiluce fixings on the tail gate and more modern lights as I couldn't find any of the correct lights, but I knew it would be a compromise as its a trailer so I cant afford to spend too much on it.
Looking for the correct T plate now
I cant find much else about them?

Have to google some  more
