This is the original model that was submitted by George Campbell to the US Patent Office in 1865 to show the details of his invention.
The models were required by the Patent Officer in order to establish the merits of a patent request.
This washing machine was patented #52,265 on 30 January 1866. The model bears the original signed patent tag as well as the inventor's tags. It matches the machine in the original paperwork.
Copies of the original documentation is available at Google Patent Search online:
I purchased this particular example from Cliff Petersen. At one point Cliff Petersen owned the largest collection of patent models in the US. His purchase of a huge crated group of models saved thousands of models from obscurity and possible destruction.
