Just accured a Frandee, model D, S/N 37, Snoshu, made by the Utah Scientific Research Foundation with the "retracting" stearing ski out front. Found it in a farmers "bone yard" while out bird hunting 3 weeks ago. The owners family had purchased it around 1960 and used it on their farm in the winter to feed the cattle. I am planning to restore however before I get to far into the project I would like to gain some knowledge on the unit and get any historical photos so I can correct the few "modification" it has. How close to original should I keep this unit since I am assuming it has some historical value? Does anyone know of any other Frandees out there that may be being parted out? This is my first snowcat and any tutoring would be greatly appreciated.
