You've got a tape from the IBM Magnetic Tape SELECTRIC Composer. Attached is
an IBM Journal article describing it in detail....

Anyway, I'm wondering if anyone can tell me what vintage it is and what

Tom, back in about that era IBM produced a thing called the MTST (Magnetic
Tape ???? Typewriter). It has been eons since I laid hands on one or
even seen one so my memory is pretty fuzzy, but I'd not be surprised if
that was not the use of that tape.
