Well, these machines were no longer made after, hm, 1960 or so. I think the last model was manufactured in 1959; I don't know how much longer after that they were still being rented or sold but eventually they were no longer available. My friend in Racine stayed on with the company until the early 1990s part time, and he said even up to that time they would still get inquiries for repairs and parts, and he did continue fulfilling those orders until he left the company. After that, there was no longer any support at all for the machines. When you'd call the company about it, they would still for a while refer you to him as he did keep up a small inventory of parts, but eventually he went into total retirement and just got rid of what little bit of stuff he had left.
