I've not only Velocette material in my archive and this photograph is interesting and historic.

On the back is captioned..."The Founders"....

This founders image date is likely early1930’s The journal on desk in right foreground bears a title and date, a higher resolution scan reveals "Leading Advertisers 1930"

Seated signing document, Walter Davidson, President.
