I've written some fairly extensive notes on the subject.  I posted them
in two short articles on Mel Wright's website on busker organs.  The
more recent one is

  Carts for Small Organs by Wallace Venable
  http://www.melright.com/busker/jsart98.htm 

It follows about five years of experience with the one described in

  Box-Cart for a Grind Organ

Since I wrote the "Carts for Small Organs" piece I have constructed one
along the lines of the folding cart. I don't have a photo of it posted,
but it is the blue cart in two COAA Rally photo collections:

The Mel Wright website also has another design:
