One easy solution is to simply buy another Bridgeport mill head. I'm going to
have a clean step-pulley J-head available shortly. It was fully rebuilt about 4
years ago and has had very light hobby use since. Of course, it isn't varispeed,
but then it's clean, complete, solid, quiet and WORKS.

Ok, I put money down on a Bridgeport Mill, SN: 131234 (on the front
end of the area between the ways above the crank that moves the bed
front/back... missing the MOTOR!! But relatively inexpensive, and
local... so far good.
The head looks pretty much like this one:

I think that is an old 2-J head. There are a couple different designs,
although the changes are all really just cosmetic. Newer models have
a plate that covers the speed dial, with two slots exposing the current
speed setting. There is a "mask" that blocks the reading for the wrong
High/Low range setting, based on the position of the high/low
range selection. it has high and low speeds marked by a rabbit and a
turtle. The direct drive clutch and the back gear handle are linked to
this by a rod.
