This is the best example I have ever seen. It was recently featured on an NPR science video about the history of early medical devices. It still has all the original glass bottles, air tank and air pump. The oak table is amazing with the heavy turned legs ornate brass fittings and oversized crystal ball and claw feet. The table is also signed on an engraved plaque. Included are framed prints of the patent drawings plus a copy of the original ad. It claims to be the best treatment for all diseases of the respiratory organs. It does this in the most decorative way. If you are a Quack doctor this can be a nice source of income for you… SOLD
