Found this funky trike in Foley, Alabama. It appears to be homemade. The seat was on a big threaded rod so you spun it to raise or lower it. The axle was a solid rod, leading to the skiddiness that the differential was invented to remove. The back chassis appeared to be part of a go-kart frame, and the front was just square steel. The chain tension was adjusted by unbolting the bottom bracket and sliding it forwards or backwards. With the apehangers and huge seat, this was quite a cruisin' trike.
