Thanks everybody for your help, much appreciated. I was erring on the side of yes too, but needed some verification. In case anyone is interested, the reason I am trying to establish if it's the same man is because:
My GG Scales worked as a Wheelwright at a motor and coaching company called Wiggs up to the 1930s, but then moved to the Bermondsey Borough Council Wheelwrights' Shop. I thought he moved there in 1941, but I found a photo of the council department (attached) from 1937 which shows he was there sooner.
Another photo we have of him - the only one my side of the family had - shows him and another man putting up wooden bleachers i.e. crowd seating on scaffolding in a park, which I have put on rootschat previously here:
http://www.rootschat.com/forum/index.php?topic=705871I believe they may be pictured erecting bleachers for the crowds to watch the coronation of King George VI, so the fact that the other man is his colleague from Bermondsey Borough Council strengthens that since it would indicate that the people drafted in to erect the bleachers were from government departments, which is more likely than using private contractors. (The men on the team making the bleachers may also include colleagues from the Carpenters shop of Bermondsey Borough as well since the two departments were closely linked, having previously been one department, and both obviously working with wood. There is a photo of the carpenters shop at the council too though it's too hard to see the men to compare faces).
My GG Scales died in 1946, and my grandad in the 1980s, so no-one is alive who would know what the picture shows, hence the difficulty. For anyone with Ancestry who is interested in the delightful Wheelwrights of Peckham and Bermondsey, the details I know are here:
