I was referring to two 47-teeth gears - one is on the worm, another one is on the output shaft of the gear box of my classic EQ6 (gearbox with 131 reduction).
Also, I mentioned the last stage of the reduction in the gearbox that is 1:3, and the effect of this is visible as 3x higher frequency un the PE photos..
The Synscan EQ6 mount has slightly different reduction: 200s/rev motor, 12 (or 20?) teeth gear on motor shaft, then there is middle-size transfer gear (with rubber spacers?) and finally larger gear on the worm shaft. The reduction ratio is determined by gears on motor and worm axle [middle gear size (transfer gear) is irrelevant]
