Hi All.
Thanks for your responses and ideas. I actually solved this one by the same process as you, in that I tried to interpret the 4 items in the design. A beehive and St Peter rang a bit of a bell, as I knew that Manchester has a beehive associated with it (representing industry) and St. Peter's Field was the site of the Peterloo Massacre. Tried all the various regiments and then had a "bing" moment! Manchester Unity and the Order of Oddfellows. Yup, it turns out that my uncle must have been a card-carrying, tie-wearing Oddfellow. I never knew that! I still don't know what the other symbols represent but I may dig around and satisfy my curiosity. Thanks again. Rory
