Early Days of Motor Byking

My Dad came accross this photo of him - that's Dad standing - along with his brother and cousin on an old BSA Combo as its captioned on the back of the photo. It's dated 1948 and is most likely in Derbyshire. Dad's motorcycling experience culminated with owning a Lambretta for a number of years out of Sheffeild University. (Can't find a picture yet.) Notice the spelling in my title? That's how it was written on the photo. Interesting. Awesome looking bike and with a side-car to boot. Anyone else have some cool old bikes to share over these winter months.
