Searching through some archival photographs yielded these photos of a 1922 Henderson 4 (possibly the Deluxe) and a 1931 Henderson 4. Both machines have been modified by the owner, but perhaps the words on the backs of the photos best tell the story.
Have just learned from the AMCA forum that the machine above is currently owned by Doug Strange. Click here to read the story. This photograph does fill in a couple of the details. (Sept. 26, 2009)
