Jon, I have a full set I will send you if it helps. I do not know how they were mounted. I removed them from an old devlieg and tried to sell them on Ebay at one time with no takers. If they will help the cause I can send them your way.

I finally was able to buy some sections of Inductosyn scale on eBay for a price I could afford, and started working with it. I found that if I put a 120 - 6.3 V filament transformer in the excitation circuit, the excitation driver on my board can drive it without overload. I then get up to 50 mV P-P out of the sense coil. I then set up a 100:1 differential amplifier, and get signal levels that would be compatible with the AD 2S1200 chip that decodes the Sin?cos output. I don't have a complete Inductosyn set, so i am using additional sections of the scale as the sense winding. I would guess the real sense windings are shorter, and the pair of Sin/Cos windings are less than one scale segment long. The scale segments are 10" long, and appear to have a winding pitch of .1". The winding is about 2" wide. One question is how close are the windings spaced? Right now I'm using a piece of printer paper to space them apart, but that is just a guess. Thanks for any info on how these are typically installed on actual machines.
