I've always heard that the Illinois Burlingtons were sold cased-only, in their own marked factory cases.Would anyone know if they ever had a marked silveroid case, or were they all YGF? And did they ever offer uncased movements?I know many of them were recased over the years....Thanks!

I hav e heard that the "Burlington watch Co, Chicago" was an Illinois Contract watch customer of some quanitty. The question ramins who cased and timed the watches?
