This is my only source of this information, but it seems to be confirmed by catalog images. The white blaze on the rear mudguard was required by English law in October 1934 so we can assume this bike was made sometime after then. It seems Raleigh dropped production of the 26" wheeled heavy roadster at some point with only the 28" wheeled version remaining. If we use the catalog data (which is not always complete) to find the last 26" wheeled heavy roadster to find an end date and use the mudguard blaze to figure an early date of 1935, it gives us a likely window of production for this bike. It might be narrowed down further by the 24" frame option.
