Rostron Formula Fords
Our club, RMVR in Colorado has two pre-1973 Rostron FF's. That's pretty unusual since there were only ten Rostron FF's produced, and that total includes a CT-1 prototype in 1969 and an unknown quantity of CT-2, -3 and -4 production models. History for the Rostron FF's is pretty scarce; per Steve Nickless, Carl Rostron and Mike Thompson started the company but Thompson acquired full ownership in'77, then sold it in '78; the name Nigel Fright (?) is associated with the marque in the eighties.
One of the Rostron FF's in RMVR has FIA papers citing the car as a '72 CT-3, (ex-Paul Sleeman), has a removable dash panel and the bottom chassis rail is square tubing. The other car may be an earlier version--it has a fixed (welded) dash panel and uses round tubing in the bottom chassis rail. These appear to be the only differences between the two, and we think the "other" car may be a CT-2.
Any recollections, contact info or best guesses would be appreciated.
