I’ve been into air-cooled VW’s for over 30 years and as stated earlier this is not a “barn-door” but a double door that was an easy order from your local dealer back in the day. The bus had many names throughout the world i.e. bus, kombi, samba etc. here in the US it was known as the Bus which came in 4 versions from 1950-1967: Standard, Deluxe, Deluxe Micro (21-23 windows and a sliding ragtop ) and Westphalia (the camper). Hers has some aftermarket or home made conversion kit and the side windows are also aftermarket.
As for her story where is the proof: i.e. photos or documentation. If it truly has been sued by the US and it is a “true court case” that documentation would be public record and therefore she should have a copy of it to back up her claims. Or try to have past registrations or something other than her word of mouth otherwise any classic vehicle owner can tell tales of grandeur about their vehicles. Sorry but I’m not believing it.
