Hello, I'm looking for information on a Brabham BT23B, I have found two entries for such a car as follows:
Non-starter at 1969 Race of Champions with Climax engine, driver Roy Pike, entered by either Antique Automobiles (i.e. Colin Crabbe) or Jack Smith
Took part in 1969 Canadian Grand Prix with 2.8 Climax engine, driver John Cordts, entered by Paul Seitz
Are these the same cars? Was the car originally a BT23A? I can't find any info on this 23B type, what was it built for?
Many thanks in advance if anyone can help.
