I got my "new" Marvel model #8 home and realized it has a gear-box built into the motor with four ratio speeds. I have heard of the two-speed motors and the single speed motors. I have never seen one of these 4 speed motors yet it isn't something added later as the placard listing the speeds of the machine has the 12 different speed options listed. Anyone seen this option before?
Minus any duplicate speeds. You have 2 ways to get 60 fpm, so technically its only 11 speeds
