A. Brian Robinson (debut Croft 12 Mar 1972) = B21-72-4 B. Trevor Twaites (debut Croft 12 Mar 1972) = B21-72-2 C. Pete Smith/Dave Wepton (debut Croft 12 Mar 1972) = B21-72-3 D. Red Rose Racing/Montjuich Tergal: John Hine (debut Paul Ricard 9 Apr 1972) = B21-72-7 or B21-72-8 E. Red Rose Racing/Montjuich Tergal: Jose Juncadella (debut Paul Ricard 9 Apr 1972) = B21-72-7 or B21-72-8 F. Red Rose Racing/Montjuich Tergal: Niki Bosch (presumably a B19) G. Canon Cameras: John Burton (debut Paul Ricard 9 Apr 1972) = B21-72-12A Canon Cameras: Bob Wollek (not ready in time for Paul Ricard 9 Apr 1972) = B21-72-14 Max Olivar (not ready in time for Paul Ricard 9 Apr 1972) = B21-72-6 Numbers 5, 9, 10, 10A and 12 had gone to Italy, Switzerland or the US so I'm sure we'll see them later. |

For Snetterton 31st March add Fletcher, described in Autosport as new B21 and also not allowed to practice with the other 21s as no rollhoop certificate was available until after official practice. Autosport goes on to describe it as "built from various Chevron pieces and call it a B16/19/21!

Reading through the various reports one is struck by how often the same car is described in the rubric as a B19 and in the results as a B21. Externally, in the photos of the time - reproduction not being what it is today - as the rules changed to mandate the full width screen and the rear wheel covering tail it seems to be almost impossible to differentiate between 19 and 21 (at least that I can see). Headlight recesses (where fitted) seem the only clue.

Simon may i correct you on 1 point ( prepared to have sand kicke dback in my face and cook a Pie or should i make that a Pye! if wrong)
B19 car had closed cockpit over passenger seat and roll hoops where not full lwidth in rules ( see lola T290) rear wheel body work open B21 had to be open cockpit over passenger seat full cockpit width rroll hopp rule implemented but rear wheel arch bodywork open B23 as above BUT rear wheel arch bodywork HAD to be coverd in so rain/ dirt etc could not fly out hence B23 has a bolt on body piece to the tail very neat where as the t292 lola had it all moulded in with rear wing but T290 cars cobbled up any old plate they had to fit their cars I also understad that in 72 we had a change in tyres as slicks came along and some cars run the treaded tyre some tried slicks these had different side wall heights ad as ssuch had a bearing on rear wishbone lengths camber castor ride height and this is where the B19 to 21 would also have been "modified" now what i want to know IS there a difference in B19 chassis to b21 The b16 as we know IS different hnce why 5 b16 cars get stripped down of core componnents ie engine gearbox uprights brakes wheels etc and fitted to new chassis body wishbone i now take 2 steps back and wait for the fall out! |

A pedant writes, as far as I am aware all B19s had full width 'hoops (except the 16s/19 prototype) and in the full international Group Six races in 1972 all cars, 312PBs, Alfas, Chevrons had the rear wheels covered in behind. The 2 litre series did seem to leave them open - I wonder why the rule should be different at the same time? And that was more than one point so look forward to my pie........

The 1972 Gp 5 regulations required, from 1st April, that ''an opaque and non flexible part of the coachwork must extend downwards behind the rear wheelsof the car to 20cm minimumfrom the ground and cover the entire width of the rear wheels and tyres'' The waiver for the opening in the bodywork, 1972 required symmetry, was not extended so all cars had to have a symmetrical non covered opening for 1972. Shall I go on? |

Pie in the oven!
also at the time the rules of Group 5 and 6 where utilsed in these sports car events ( firknows the main difference but was it wheel width?) and did we not have 2 ruling bodies? I did read a snippet in AS late 71 i think about the Gp5 and 6 car rule leading to confusion as they would/could run together in events-it did not elaborate on the differences |
