Can anyone please share the catalog pages for the 1910 model? I wonder if the part is somewhat interchangeable, thus increasing my chances of finding it. If you know what that part is, even better, I wonder if there are other models that have that same wheel, but with the S37 size it is unlikely.

unfortunately 37 size watches usually have parts larger than other watches and the ability to interchange with anything in the universe is nonexistent almost probably. Then parts catalogs in 1948 was scanned in some incredibly high resolution with the incredibly huge file size which is why no one in their right mind is going to attach it to anything as huge PDFs clutter up the message board. To get anything that was it resembling readable I had to increase the file size and it still isn't the best and it is a rather huge file for just four pages. I think my copy was purchased off of eBay somebody probably had a disk of stuff.

Repivotting is an option but you'll need the tools and a lathe

Actually, as the wheel is big, it is possible to repivot it without special tools. Just good hand drill needed and proper drill bit of the correct size, close to the pivot size. If needed, I will explain how and show some pictures.

...When I remove the pallet form and give it just a bit of a wind, the train spins nicely, even with just a bit of a touch to either of the two mainspring barrels - yep, it has two!...

Well, this statement brought all of us to delusion. It appears now that the train was blocked by the wheel with broken pivot

Does this have the same movement?

There is a 1940 parts catalog  viewable via this page, though it's not downloadable and a real pain to read..

I found an alternate link with direct access to each section, this is the Automobile & 8 day link:

Part number 28172 found me a set of wheels on ebay! Now I wait for delivery and will update the forum once I plug in the new wheel.

I will try to buy this one if my wheel purchase does not work out. Escapement parts look good and it is indeed th same model - 1910.

The new wheel is in, but the watch still stops:( Before I touch the bankin pins, I will strip it once more and clean both barrels to make sure the springs are giving it all the power they can.

I haven't followed the discussion in detail, but I'm thinking that you must try to locate the source(s) of the problem. If the problem is that the barrels aren't clean enough that's what you need to do, but I would say that is the least likely source of your problem. Analyse the watch in function groups as show by Kalle Slaap.

I see a Waltham car clock on eBay now at 15 or so, might be another one for parts if needed...

Triumph! As many have suggested escapement was the culprit. Despite the pictures looking good, I started to examine each piece independently and when each piece worked separately, I finally got a closer look at the balance wheel and touched the impulse jewel. Although it looked right, it wobbled on me. 

I have since shellacked it in place and the watch is running nicely again!

Thank you for all your help. Lesson learned - examine typical suspsects first and up close.
