Re the MRS Brabhams in the photo I think there BT18's or BT16's. The side of the windscreen on a BT21 is level not curved like the BT18 and its predecessors. Harry Stiller did switch to BT21's but they were blue with white stripe with red edging similar to the works Titan colours.
James, I think that Lanfranchi's car [#6] is a BT21, based on what you are saying. According to Autosport, Stiller used 'last year's car' [a BT18] at this race, because the second of his BT21s was not yet ready. That would bear out your observation of the curved bottom edge to the screen. Stiller bought two BT21s, and they were run by MRS, in yellow, in the first part of the season. He took them to Charles Lucas's outfit later in the year, which is when they were painted in Titan colours.
Foulds's car is, I think, a BT15, though it might well have BT18 bodywork by this point in its life.
Thanks for the picture Andrew, any more F3 from that meeting?
