I have pictures of the inside of the gear motor in chapter 7 of my book,
"Creative Projects with LEGO Mindstorms".
The motor is geared down by a factor of 13.56 --- 10 tooth to 44 tooth gear,
then 12 tooth to 37 tooth gear. 12 tooth gear and 44 tooth gear are on same
axle. I don't know if this hits upon what you were looking for!
