Hi people. I have been reading your wonderful posts with especially the photos for some days.
Many pages ago you were discussing the car registration COM1C. Moss garage was mentioned. I can confirm that Moss Garage was at 1163 Chester Road. I worked at Contractors Plant Group which was at 1161. The CP Group had purchased the site from Hangers Ford in around '69/70. Here is your picture of 1157 dated 1968. You can see the post, just about, but the "OL of the PETROL sign is visible. Then look at my picture taken from inside 1161 showing my Austin-Healey Sprite in 1960/70, the sign is there as is the PETROL sign on Moss Garages forecourt. Plus a pic of me with my MGB in 1970 oside 1161.
I seem to remember that the house next door [1159] was new. CP Group purchased a large part of the rear garden.
