Some info on Neumade tables before the years go by and I forget ...
Neumade made many different tables that allowed you to clamp (or bolt) several different rewinders to. This seeemed to be the way things were done from the 'beginning' to the middle 1950's. But from what I can tell, (from the company documentation) Neumade's first 'integrated' rewind table was the 'Power Rewind Table 35/70.' This model came out of the design that was originally made for Cinerama, and started selling in the late 1950's for 70mm theaters. (There are several earlier 1950's dated photos in the archives showing tables with motors built-in holding those large Cinerama-type reels.) The PRT 37/70 originally only had 1/2" spindles, but after the PRT Ultra was released, you could get a retro-kit to make them changable. It had a foot pedal you pressed on to apply more rewinding torque. It was discontinued around 1975.
Most of the 'head' parts (spindles, collars, shafts, etc.) are still available. But (sorry) the motor, motor cradle, foot pedal parts, drawers, panels, legs, etc. are not made anymore.
The Power Rewind Table 35/70, below:

Not every theater needed a heavy-duty table, so in the early 1960's Neumade also made the PRT Ultra. It was designed with changable spindles, and a dead-side foot pedel to control tension. The motor controller is an AC controller, which means the low speed regulation is not very good. Most spindle parts, heads and the controller are still available. I saw a few white table tops in storage a few years ago, so if you really want one they might still be there. The PRT Ultra was discontinued in 1995 or so when the PRU Ultra II came out.
PRT Ultra:

The PRT Ultra II is the current table. It uses a DC controller for a smoother speed control, a feature where the tension on the film stays constant as the rolls on each side get bigger/smaller. The spindles are different than the ones used for previous tables. No operator nowadays wants to stand on a foot pedal, so it's gone from the design.
PRT Ultra II

I have newer manuals and a 'spindle guide' for all these tables which I will email Brad & Co. tonight.
