My grandfather, wounded in WW1 was unable to do a normal job because his hand was crippled, worked for a few years for what was then known as the 'Gas Department'. I think this photo was on the front of one of their booklets which gave a precis of the history of Birmingham. I had this book when I was about seven, but don't know what happened to it. I did not think for one minute that I was right, it was just a stab in the air, but I am pleased.
