Fascinating photograph, but it confused me. My first thought was 1956, but I could not fit the landmarks with Fairfields' yard. Then I realised it must be the previous Empress of Britain, 1931, which makes this aerial photograph even more unusual! If so, this is Clydebank long before the blitz, and almost unrecognisable from today's town. The strip of water beyond the Clyde is the Forth & Clyde Canal, wending round the south side of Singer's huge works (now long closed). Looks like a steam yacht in the fitting-out basin, and a pair of small sterns in the shed on the left - were they submarines being built for the coming war, I wonder?
