I think LSPA in Hockley, TX has a couple of these in rough shape. Isn't there supposed to be either a small pool cue or chalk connected to it by a chain?
Yes, normally there is a chalk holder attached to them. But, I don't want to encourage anyone to use chalk on it.

I contacted LSPA to see if they do indeed have any of these machines. I am looking for another one to restore. They don't come up very often for sale. I have been looking for another one ever since I bought this one.
