Not a smoking gum, more like blanks.
I was born in May of 1955.
When my draft classification came up, My draft card read “1H”.
I had never done anything to affect my classification, I had no relatives or contacts who could have done so for me.
I had no idea what 1H meant, none of my friends had gotten that classification.
I actually called the draft board for an explanation.
I can still visualize the sergeant who answered the phones crew cut, he had a deep command voice, with a hint of a drawl.
His reply was as follows -
“Well son, we believe this war is about over, it is not expected that your service will be required, your classification is 1 Holding”.
“If the situation changes, you WILL be notified”.
So from my experience, “1H” is just luck of the draw, too young to be caught in the Nam’ draft, then the draft was ended.
thanks, that appears to answer the questions asked in the article.
