@lonekazoo So just to confirm, these trailers were made by Brenderup and they are still in business. TrailerTek sells a lot of the accessories and granted they are in the UK but I had good luck purchasing from them. Here's the page you can check out: Brenderup Trailer Parts - TrailerTek.
That said, I think there may a dealer here in the states that can get this stuff plus @perkj mentioned a few pages back a manufacturer of similar trailers that have lids, they might be a good source for a custom lid.
Good luck with sorting out your trailer, it looks as though it gets a good bit of use!
