The 3rd group of Patent Models from the 1800s
Even if there had been 250,000 models submitted to the Patent office over a period of 50 years, from the 1830s to the 1880s, after the major fires, they are indeed rare. One of a kind is a common way to describe them, BUT, each one is different from others even when there might be a group of 20 models of "improvements in sewing machines" they are all different and represent the dreams of many.
I will display models from my collection and those of other close associates.
