GR,
When new, the 866 was built like this: it used a short accumulator spring under the piston, it had a 3.2 ratio KD servo lever, it had a controlled load KD servo with single outer spring, it had a plain governor spool valve, a purple coded valve body, a 4 pinion front and 3 pinion rear planet carrier, 9 springs in the front clutch retainer with 4 friction discs, and it had a standard input and output shaft (not specially heat treated). Forgot to add it has a heavy inner governor weight and a green spring in the governor.
