I had the privilege of using some of these machines when they and I were much younger. The sander, horizontal mill, yet unseen Greenerd arbor press, Jet 125 VS3 drill press, Challenge surface plate, Drafting board and machine, and a couple other pieces came from the company I worked for. In about 2000 they decided to close down our machine development department and the machine shops associated with it. I was assigned the task of liquidating the assets of a couple machine shops.
All the assets were offered to other shops and production facilities within the system. When all was said and done the remaining equipment was supposed to be sold to the scrappers. I negotiated a deal with the management to purchase the machines at the same price the scrapper was willing to pay. The only caveat was that I not resell any of the equipment for at least 5 years. The 5 years came and went nearly 15 years ago, and I still have all the machines. Not only that I was able to purchase more from other shops they closed a couple years ago.
Between those machines and the ones that came from other shops in the area my shop is nearly full. About the only items remaining on my somewhat inactive wish list are a Moore #1 jig bore machine, and either a Fosdick or a Standard Modern radial drill. There are others I would consider if they happened to come along at the right time and price, but there is nothing on the "must have" list.
