I love these cobbler machines. This Adler 30-70 is the last model made by Dürkopp Adler in Germany. Other manufacturers make patchers based on the older Singer 29 cobbler machine.
Below is a Singer 29K I restored with a great local artist -
Amanda Lynn. This cobbler machine now belongs to the Goorin Bros. Hat Company in San Francisco.
These machines have been made for over a hundred years with very little change. Like someone once said "...if it's not broken, don't fix it." (see my other blog post on the Adler 30-1)
