Completely agree that some smaller trailers are just what is needed now that there are finally some decent 1:32 classic tractors appearing from the 1960's,70's & 80's.
You only have to look at the Classic Combines website for what are v expensive examples in 1:16 that could be made far cheaper in 1:32 by Britain's or even better, UH.
As mentioned before on this site: What about a NH 717 or 719 forage harvester or Claas Jaguar trailed. Perfect for the County 1474!
Don't expect others to agree but why couldn't UH make a 2 wheel drive 590 rather than the 4 wheel drive that is far less common.!! Seen good conversion on web but bonnet is too long for it.
