My father was rejected as a 4F because of stomach ulcer. He ran a shift of women building bombs and torpedoes at AOSmith in Milwaukee during the war.
He had two young daughters going into the war and three at the end of it.
As a young lad myself and other kids would stand on 35th Street across from the AOSmith plant building watching the
red hot bomb casings come out of the ovens and presses that formed them, 24 hours a day 7 days a week.
That plant produced pipe for oil/gas pipelines before and after the War.
