Here are photos of the Marble City Special. It is named after David Morrill´s home town of Sylacauga, Alabama, which has a white marble quarry and is known as "The Marble City".
The bike is a "Cutdown" style bike with a 1921 Model J motor in a 1926 frame. It runs a total loss battery fired ignition, Schebler 3/4" carburetor, and an extended racing intake rocker. It runs a 1925 three speed transmission with a modified suicide shifter.
Grate thanks for the pictures and information David . . .
