My thanks go to Richard Groetzinger for sending me this picture of his 1958 Tri-Wheel Thrift-T. Richard writes:
hoping you could help me any info you may have regarding this vehicle. It is titled as a 1958 but the owner thought it may be a 56 or 57. It has a Onan twin engine and Crosley drivetrain with a 3 or 4 speed gearbox....I almost got thrown out of the house when I brought it home!
More pictures of this vehicle can be seen on the Tri-Wheel page in the A-Z section of this site.
