Found that module number in a copy of the Option-Modules List.  It shows that it’s a CSS item.  That would explain why few have ever heard of it.  I wonder what punch it used.  I’ve seen people use CDC punches (415) as OEM devices.  JWS mentioned someone interfacing a machine to a keypunch.  That’s a bit of a desperation tactic, it would be extremely slow.
