[GreenKeys] oiling tape?

[Pete Lancashire]

For a shop that does tungsten carbide forming and machining the making
of the pins for something like a teletype would be pretty easy to do. Before
we sold off all our maunfacturing to Asia and down south even in little ol'
Portland Oregon I knew of at least three shops that if you took a the two
size pins or a drawing a few days later they would have made for you nine
pins. Worse case they would have to order the raw stock and you would
have to wait another week.

All those small shops are now gone ...
