What makes you say it used to be a RHD car?
Sounds like the $3-500 "Genuine US Army Jeep" ads of the same period. You had to pay for those to be shipped from Europe.I.....Restorer's" classified ad page always had photos of Phaetons in South America ...the catch as I recall was the buyer had to arrange and pay for shipping and import duty from South America.
