There was a very nice luggage trailer painted to match the MGA Coupe that was towing it. Seen at NAMGAR GT-48 gathering in Memphis, Tennessee in June 2023. Have not seen this model before, no tags on the trailer, and no time to chat. I did not get to talk to the owner so this one remains unknown. --- No side marker lights implies 1968 or earlier production, but the design style looks much newer, like 1990's or later. If it was a one-off home built, it was a very nice job.
