Hi Richard (Vitesse), thanks for the addition. It would be interesting to see a picture of the former University Motors Ltd office at 105, Cheyne Walk, Chelsea S.W. 10th
It might be worth contacting the chap who runs this blog - he's the Local Studies Librarian at Kensington Central Library. The actual site of what was University Motors appears to have been at the corner of Cheyne Walk and Milmans Street.
