Seller says this is a copy of a Watsonian sidecar made by International in Minnesota. Florida sidecar products has some info on their website.
There's a very long build thread on ADV by a guy who mated one of those to his V-Strom. I never knew what car it was. Thanks for identifying it. Build thread is called "The 12x12 Build" because he built it inside a 12 foot by 12 foot shed.
Much bigger tire on the car there. Wonder what he did with the sidecar fender?
Illegitemi non carborundum est!
Fairly sure Al only got the body to start with.
I had a Vstom at the time so watched closely.
The leading legs finished up in Australia down the road a bit from mine on a friends bike.
Wonder how Al is getting on now?
