A bit of a scruffy photo this one but the image is nice. Easy enough to identify as a BSA B31 rigid, perhaps 1949? Looks like it is a brand new purchase and all shiny with a canvas pannier set and possibly a personalised reg number. Sir is sporting a natty leather jacket and gloves at a time when most folks didn't have much in the way of specialist riding clothing.
