F3s and 750 Specials and British sedans I can't identify. Clearly 1954 or later as it is after Druids Bend had been constructed, but not much later. Tunnel already exists. Note the skinny pit lane on the outside! Is that Masten Gregory at the end of the video? What is the lovely sports car at 1:27? Should be easy to identify, but I can't pin it down mentally because it looks like everything with good fastback. [well you'll have to visit YouTube by clicking on the black video]
Fantastic quality footage, incredible ! The car must be one of DB3S models. That car was as beautiful to drive as it looks, at least if my physics (unreleased) were fairly accurate. http://astonuts.free.fr/PAGES/DB3SFHCE.html
Yes, appears to be 113, where the fenders were replaced so they weren't cutaway. Truly one-of-a-kind out of the 3 production and 2 factory racer models!
1954 - 1959 The photo above looks like it doesn't have the tunnel out of the midfield paddock as shown in the video.
Few comments in YT say it is around 1958. I wish the track remained to have this fast flowing mid section as it was originally.
Some comments were based on identifying Lotus 7 in the races/paddock, but I those are Lotus 6 instead. Lack of Lotus Elevens or production Elvas or Lolas suggests an earlier year to me, but maybe that club didn't sanction any races with those.
