Based on what I see in mine (and its cruder ancestor in my Grafonola 75, 1915), the auto stop is a mechanism that works in conjunction with the motor via levers - a la the brake/stop/start underneath or above the motor board. It is completely outside the sound reproducing system. It should not have any connection to / intrusion upon anything from the horn all the way to the sound box, so it shouldn't contribute to leaks.
Very odd. What model is yours Jim? (btw There's a nice 2-page ad on eBay right now that has photos of the 1927 models, mine is the lowest end and is only mentioned parenthetically, haha.) I agree that for Columbia to omit this in the higher end models (especially if they went to the effort of using velveteen) is surprising. Do you see anything under the platter that might suggest there might once have been an auto stop?
