[Simon Hadfield]

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!

[Simon Hadfield]

At Nurburgring Interserie the Gray B19 is described by Autosport as ex John Lepp and also mentions B19s for Dupont, Ralf Walter and Zaborowski

[Simon Hadfield]

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.

[driftwood]

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!

[Simon Hadfield]

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........

[driftwood]

Dieter Quester B21-72-15 sold new to Bosche who run the 1st BMW M12 engine- this car is later writen off in a euro 2 litre race never seen again

Roger Heavens B21-72-16 ( main parts kit from Chevron and his B16-35 running gear- chassis body WITH plate sold to usa via 1972 AS advert asking price £750

John Gray B21 is in fact B19-71-9 RRR Lepp car lter carries B21-72-24

Simon said Because my columns are poo I should make it clear that he gives Martin Raymond in /26 in 72 and /27 in 73do you mean here that he raced in 72 events B21-72-26 (sells this car ?)and in 73 he has b21-72-27 car or gets his 26 re numbered 27 or he has the car as B23-73-27

Zabrowski in 72 races B19-71 -3

[driftwood]

Was B21-72-12 Clemens Schikendanz turned into 12A Canon Cameras/ John Burton or are they really the 12 & 13 cars?

[driftwood]

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

I have chassis 12 which is alive and well so I don't think it became 12A. Andrew Schryver has 12A so he probably knows the history of that chassis. I have FIA papers, Wagenpass and notes from previous owners. It shows it went back for an upgrade to a 23 (I have the rear wheel covers but don't run with them). It also shows that it was run with a 3.0l Porsche engine at one time.

[allenbrown]

Thanks Delbert. Could you give us as much as you can on this car please - owners' names from Schikendanz to today, race dates, etc, etc. If we can nail this car's history from a documented appearance in period to today, it's becomes our first 'nailed' B21.

Also, do you have any information about the Oldenkott Tobaco B19 ('P' in our listing) that Clemens Schickentanz raced in 1971? Could this have been converted into his B21?

Last question but a key one - how have you identified your car as B21-72-12? Does it still have an original chassis plate?

[Simon Hadfield]

Andrew's car has its own history and photos with FVC still in car when it first arrived in Belgium. The funniest thing was the rubbishing some of the "experts" gave the 12a number....cue the Montjuic book. One feature it shares with Lord Laidlaws B16 is that all the pots, oil tank, fuel collectors etc are the gas welded originals. Andrews is still the most unbuggered about example I have seen to date. The other feature they share is that both have lost their original chassis plates but have all the Arch numbers (matching crossmembers etc)

[driftwood]

Allen you know all about the Roger Heavens B16-#35 car AND the B21-72-16 cars lineage and history
its well documented in AS reports & adverts and the B21 running in euro and angola races as b21/23 and B23
Then lying in angola till the late 80`s after the conflict and to sweden & back to UK coming thru my "hands"
B21 is ready to race again as the REAL b16-35 is in USA with 2 fake B16-35 cars floating around 1 in uk 1 in europe

It will take me a while to pull it all together but I will set out what i have when done.

[allenbrown]

Simon, how complete is the history of Andrew's car? How far can he trace it back? And if it didn't have a chassis plate, how did he know it was 12A?
