Video from Pennsylvania Hillclimb

 This short film comes to us thanks to Dwight Egolf, the owner and driver of the car at that time. I believe the film is from 1973 and the Pagoda Hillclimb in Reading Pennsylvania.

Guillaume Soumagne buys Bertil Sollenskog's Formula S and ships it to France

Guillaume Soumagne has purchased the former Bertil Sollenskog car, which Bertil had purchased from Leon Mull. Bertil started the restoration but sadly passed away before he could complete it.

Guillaume has shipped the car to France where it will be given a full restoration. It will join the Motor Sport Service built "widebody" Sonett III that he purchased from Randy Cook a few years ago in his collection. Thankfully, both cars are slated to hit the vintage racing track soon!
