I cant find out anything about Lancaster cars.
When I bought my Daimler VDP DDS, I sought out the PPO, who was a very aged gent, a complete car nut.
He took me down and showed me his two vintage cars.
One was a Vauxall 15/90 (I think, the big one anyway)
It was the other one that took my breath away though, the finest automobile I have ever laid eyes on. I think he told me it was a 1922 Lancaster.
I read a story in the paper shortly after, he had died and left his estate to the Catholic Church, who were stunned when the car sold at auction for $500,000.
Never been able to find out anything about such a car
