[GreenKeys] punched tape specifications wanted

[Hugh Pyle]

This looks like what you need:
ANSI X3.19, "Eleven-Sixteenths Inch Perforated Paper Tape for Information
Interchange".

There's a picture in MIL-STD-188-100 (attached) that shows three tape
widths side-by-side, including dimensions for the holes and not just the
tape.
(These are all the "Teletype-style" hole positioning.  Linotype 6-level
tape has the holes offset from the center track).
