MJW - That's an interesting point, horridge owned at least TWO Lister-Bristols, the earlier car was reg. no. DEN 275 and originally had a 1.5 Riley engine like the Jehu. It was written off in 1957, and it had a Rochdale C-type body - The rear quarters of the puzzle car suggest that it's also a C-type shell with a modified nose....
Slightly off-topic, but interesting nonetheless
