Correct Slide for IBM?

[painter777]

FrankD,
I've been told my IBM 3,849,505 was made in late Jan-Early Feb 1944.
Was also told by a fellow member that IBM was making about 40,000 carbines for each of these months.
Guessing if yours is 35,460 later.....It may very well be late Feb (?) 1944.

HTH,
Charlie
