Broken 4th wheel pivot on this 20F movement from early thirties. Seems to be difficult to find. Any hints where to find or if this wheel can be found in other movements?

 

If you can’t find one, repivoting would be the way forward.

 

Found one on eBay in Italy (okay for me since I’m resident in Europe as well). He had named it as “second wheel” that’s why I missed it in my first search.
