YES!
A BSA-9 Patrol Car 1930-1936.
Interestingly, the first two letters of UK registrations are allocated according to county, the "VV" on the plate of this car designates Northamptonshire - that's my home county!
This car is a Police car from the county where I grew up!
In fact I found that exact picture on
www.northants.police.uk
So here's a hard one...
...and an easy one!
