#5) Nearly '35 (I guess) "made in the u.s.a." wire lugs, decorated bezel.
Interesting, the only example appeared so far. It's even hard to be sure the case is original, but I think so.
The seller obtained it from the original owner and say it was in a catalog many years ago.

#6) Absolutely unusual 1935 Ingersoll 39 mm wide. Maybe a prototype, I think it's real and not recased.

All watches of the first serie were powered by the Ingersoll hand winding pin lever caliber ; these movements dates from around 1914.

It's reknown that in 1933 Ingersoll was struggling to keep afloat and probably Mickey watches saved them by bankrupt.
But in the late '30s, when the sale of the Mickey Mouse watches declined a bit, problems resurfaced.
In 1942 was Thomas Olsen to step in : the Norvegian shipping magnate, who escaped the Nazi occupation moving in the United States, bought the majority of Ingersoll's shares, bringing vital oxygen to the company.
By 1943 the company's name changed from Ingersoll Waterbury Clock Company to Unites States Corporation, better known just as US Time
