I can now report I have I.D.ed this frame as a Mead . The head badge ghost does match that used by Mead of B-ham as a Mead Superbe. It's design is for an early type derailer I think used with the Sturmey archer 3 speed to get 6 gears. The lugs and drop outs used were Brampton. The 1929 Brampton catalog shows these rear drop outs. I'd like to narrow down the age but even the Brits don't have much on these bikes. Their Veteran's Cycling web site shows the 1925 B-Han catalog. Maybe someday I'll have more to compare with.
