I is here!

Now, the immediate answer that I had was this might have been a CMP rebuilt by Vauxhall Motors Ltd at Hendon. This was in part of the 1925ish-on GM Ltd building that was part-leased to Frigidaire and part to Vauxhalls. The latter was turned into an export boxing plant in 1932 and from 1940 was involved in all manner of war work, including crating! In addition Vauxhalls also had a repair facility in the 'Shadow Factory' at Dunstable, where the A22 Churchills were made. Ministry of Supply code for that was 'VMD'.

However I think it more likely that this was an assembly job at one of the Ford contract plants, and time has affected the memory. Ripple Lane, Barking is a prime candidate.
