Your comment on Page 776 prompts me to enclose a photograph showing a hand-operated petrol pump (approximate date 1930) delivering petrol to my vintage Trojan (1928). The photograph was taken earlier this year at Wirksworth.
The pumps are quite unusual in that the petrol is hand pumped into the glass container which indicates the number of gallons ordered. The petrol is then delivered by gravity into the cars’ tanks.
Incidentally I have a 4.50 x 21 tyre which may be of interest to any vintage car owner.
