Hi, all.
I have zero experience with film projectors, but my husband recently acquired a truckload of films and projectors and all other manner of stuff from the film room of a mansion scheduled for demolition. In the haul was a beautifully kept Elmo st-1200d projector. The belts are melted to absolute mush, and the schematics on the service manual don't really make sense to me. I am hoping that someone can give me a rundown of which belt connects what to where. This is the whole inside:

And this is the place where the belts have melted...one of which, I assume, was the drive belt and one for the take-up? I've labeled the slots - if someone could just give me a rundown like "attach 1A to 2A with x sized belt and 2 B to 3B with x sized belt." I did see the belt packages on ebay that someone recommended, but was confused by the four belt package and the one drive belt mentioned in the repair manual!

And this is the top spot where the counter belt goes, right?

Any help would be very much appreciated - there are hundreds of films to go through and I can't wait to start watching them!
Thanks so much!

You will need at least three belts. One drive belt connects 1,2 and 3. I think in your picture it is 1A, 2A and 3A. There is a small belt that connects 1 and 2, I think it is the B's on this one.

What you think is the "counter belt" is for a long take-up belt. It is connected to the pulley/gear located top left of 1 in the second pic and the pulley/gear you point to in the third pic.

All three belts come as a set on eBay. Easy to find.

Use acetone or laquer thinner to remove the goo. Buy a box of q tips and use them. Follow warnings on cans regarding ventilation and flames.
