Greenfield Tap and Die Corporation
contains 7 Machine Screw Cutting Sizes, National Fine Thread
This was from my father, I don't know how old, 1960's or earlier ?
Judging from the metal shavings in the box it was only used once or twice.
I am looking for a new home for it,
moreso as a collectors item than as a tool,
but I see no reason why it should not work as originally intended.
