Yes, that's by coincidence my webpage.
It was tough to get Alan Manns ear at that time, took me 3 years of bugging his secretary then. Soon after the interview he went back to racing, so maybe it at least triggered something in him.
There was always some doubt that this early February car could have been also serial #30 which he might have had and is listed on Passino papers as sent to him aside from the #25 and #26 for the Liege rallye.
Yet it seems that this was indeed an earlier car or what is your experts opinion. John Grant and Brian Lews remembered more or less crips or vaguely a #3, nevertheless little documentation was so far available. The real serialized #3 was a Worlds Fair convertible as you know. Maybe Henry and Tom Mann find more in digging through the boxes that would confirm it as a S-code Allan plant car.
And then there is a longtime rumour that this car pictured here is still around in the UK.
