[GreenKeys] M15 Mystery Crank...

[Kenneth Gartland]

Hi all!

The "Mystery" crank is used on M14 tape printers
or TRP's to adjust the range finder thru the front
of the printer thru an access hole in the cover...

This is a Teletype Corp'n modification kit,
it enables Wire Chiefs to adjust the range while
testing circuits...

It is a geared linkage set up, and the crank
is differently angled to clear the keytops
while turning it...

Some of you good "Ole" Bell guys have pbly
used on of these set ups...

Cheers!

Ken
