Vintage Burroughs Mainframe Magnetic Tape Code Gauge Lot & Instructions

Includes original Walter H. Glardon instruction for their printing and layout gage, #1259.

I'm an old mainframer, but not this old I guess.  :)  I've never used one of these.

And I'm not really sure what that Burroughs branded fiberboard template is for.  I'm guessing same kind of purpose.  These all came from the same estate.
