There's the old Tamiya field kitchen too. Maybe the wheels are useful.
There was a wonderful series of kits back in the early 1960s of wagons. There was a stage coach, a chuck wagon, an ore transporter and probably others I don't remember. They were at a pretty large scale, maybe 3/4"-1'-0" or even larger.
THe wheels were one-piece cast plastic, everything else was a mixed lot of pre cut wood, wire, cloth, leather and cast metal accessories.
I've never been able to find anything on these since.
