Ron,
Even though the 29's were mainly made for shoemaker/harness makers we can sometimes find other practical uses for these old beauties. I was able to refurbish a 1916 29-4 last summer and it was the centerpiece of my collection and not one wanting to part with any of my collection, I sold it to a friend in dire need of such a machine. It sews a beautiful stitch on a 2 ply (1/8" thick a, ply) leather strap. I have a base for one and may look for a head on day.
