Sorry about the way that came out. I was looking at different parts of your message.

I'm guessing (my own hazardous guess, here) that if the
machine was for United Press, it was likely worked
fairly hard. That makes it less likely that it is that
old. Of course, it may have been in the storeroom since
1961, and they dumped it to Goodwill when they moved
offices.

In general though, it just seems that a Goodwill store in
2002 is an unlikely place to find a 40+ year old teletype.
If it is that old (and was with UPI) maybe the table had
a Telex dial set.

Ya know, if it is that old, it might even be worth buying.
If it works, you could turn it around on ebay.
