ELGIN war time electro plate.
Waltham 6 size with thick plating allowing deco pattern on it. Walthams seem to have the most durable of U.S. movements plating.
Old 18 size ASSMANN with thick plating allowing deep engraving of lettering. High quality in all respects.
Couple of Swiss complexly engraved plated movements with plating so thin (2 microns?) they look like solid gold.
