Good catch on the jewel count mercury. I would say will would need to call this an Unknown if we can't find an ad match with a 21 jewel movement or assume it is a replacement and call it an Ambassador with a replacement. With the unique shape of the case I am inclined to go with Ambassador. I did search the ads and didn't find an match.
