This is what they called a “Doctor's Speeding Wagon” which they first started to manufacture in the late 1800's. Note it does not have a fifth-wheel; it turns on a steel knuckle that can't break or come apart when making sharp fast turns.
It’s Ideal for a horse, pony, donkey or llama to pull. I've owned it for over 30 years, and it has always been stored inside. I replaced the bearings, motor bike tires; box, and the upholstery when I first got it. It comes with 2- 110vac carriage lights with flickering chandler bulbs. Note the small 12vdc battery & converter are not included. It also includes matching coloured Pony Shafts which are 67 inches long from cross member to tip.
It will fit in a small half ton truck box. Asking price is $1,000$ or B.O.

Sorry about the picture with my llama pulling it, we last our home and shop to a fire and this was the only one that survived and my printer was not working properly at the time.
