Kiwi-7, I cannot help with your question; however, if you could adjust the brightness and contrast on this photo, with the appropiate software, and post it again someone might identify the uniform and insignia.
Do let us know what you find out ... fascinating..... what was his name and what year was the photo? There are several places for WWII records on line which might show you more info if his name is a little unusual ... no chance with John Smiths for example!!
It does look like he was a captain based on the shoulder badges, but it's not easy to see the campaign ribbons as they are in b&w not colour.
poetrylover is probably right about the manchester regiment:
this link near the bottom gives more details of the regiment including the fleur de lys lapel badge
The gentleman in the photo is undoubtedly a Captain. The three pips are obvious, plus the fact that he's wearing the Sam Browne belt which only Officers are entitled to.
How poetrylover can make out "fleur de lys" lapel badges is beyond me, hee hee. I've even used a magnifying glass and still cannot distinguish which Corps / Regimental insignia they signify.
They're very clearly fluer de lys badges to me, when i put my curser over the picture i can zoom in to see them in detail, and they match the badges in the link i have added too for one of the Manchester battalions
Kiwi are you in Manchester if yes pop up to Ashton they have the Manchester's museum . You can see one of the cannons outside the museum in this picture
