Got a bit curious about the Singer and other builders of the .45 and had to Google search. Came up with this:

Singer Sewing machine company built-500 total Rarest of 5 suppliers.

Union Switch & Signal built-55,000 Second rarest of 5 suppliers.

Ithaca Arms Company built-60,000 Third rarest of 5 suppliers

Colt Arms Company built-629,000 Second largest production of 5 suppliers.

Remington-Rand Typewriter company-built 878,000 Largest single supplier.

Total built for WW2 production adds up as 1, 622, 500 . Believe these were ALL 1911A1 variants with up grades from the older 1911 models previous to WW2.
