The unit on Ebay belongs in a Museum, but for the Antique _Wireless_
Museum - it is a strech (unless you want to donate it)
The unit may well be a prototype that never made it into production, or
it may have been made by someone other than Teletype Corp. The person
(Slayton?) who wrote the description didn't seem to know much about the
piece of equipment.
Here is another "Code Permutation Tape Printer" in the Teletype Corp
Museum Books
