Hi Garry
I got a good quality trailer with Swan and then sold it as I had no use for it. It seemed to be very well constructed and the person who bought it has sinced trailed an RL28 extensively. Company in Brisbane is Belco Custom Trailers.

They may still have the drawings under a previous owner's name. I can provide the name of that person if you wish to take it further.
