[GreenKeys] oiling tape?

[Don Robert House]

Teletype pins are normally plain steel and plain steel colored.
You can spot a punch that does not need the oiled tape by looking at  
the pins.
They are shiny black and very dark black at that.

(LOL) - we were tempted on occasion to do that (put mylar in the punch -
to see how long before it became silent) but we couldn't afford to be
without punches --- ya' just don't say "sorry" to boomers needing their
tapes...

I have no idea what kind of pins the Freidens had - I suspect they were
much tougher than what are in TTYs - seems like the tape was a bit
thicker and stiffer than tty tape- and of course fan-folded for feeding
the optical tape readers...

best regards...
