I had the pleasure of completely dismantling one of these last summer, freeing up all the parts on which the grease had turned to glue and getting it operational. As far as gearing, it doesn't have any more than my Brenkert BX80 and all of them are simplicity itself to get at and replace, since you don't have to remove half the drive train to get them off. You've got to be impressed with the rock-solid quality of the machine. I mean, even the lens mount/pressure plate mechanism rides on ball bearings (which are a PITA to put back in once you've removed them!). The one I rebuilt was painted dark olive drab, so I'm wondering if it was used by the military. It's now glossy "Midnight Black" and looks very cool. You purists can cringe, but it's all I had available and if it weren't for me, the thing would be in a landfill now.) I still prefer my Brenkert, although the AA is a close second for solidity and quiteness.

Just try to get the intermittent drive gear off sometime in a booth when you're in a hurry, You ahve to remove almost all the other gearing to get it out, or the set screw out of the drum shutter that has been in for 30 years !! Of all the machines I have worked on and owned, both the Brenkerts and Motios have the largest, most complicated gear trains. Way more complex than any Norelco, Simplex, or Century. Even more complex than a Kalee 21. The thing that Motio has over Brenkert is that it is all ball bearing. A BX-80 or 100, which has no "balls" is a very heavy load for a soundhead, so heavy in fact that RCA came out with the 9050 which drove them off the lower sprocket shaft so the picture head didn't introduce any wow/flutter into the sound by being driven off the upper sprocket shaft! The Motiograph intermittent was originally designed to be all ball bearing, no bushings, although its manufacturers did finally settle on an inner bushing, while the Brenkert movement was patterned after the European intermittents. Wow! If only Christie used the same ball bearings in the P-35 as Motiograph did, they would also run for 50 years. Geez....a 50 year old still operational Christie? Thats scary enough to use as a basis for a science fiction script.
