Yes, but it's my understanding that these were photocopies .. with the look of being copies of copies of copies. That would make it difficult to get the "feel" of the paper as a typewritten page.
At the time, what was more likely, use of a carbon copy or Xerox?
carbon paper but not the carbon paper you are thinking of -- we had boxes with different colored thin sheets for copies with the cheap one time use carbon paper attached and you had to tear them off.
At this guy's level in the ANG, you would have had to jump through hoops to get a Memo copied. Just didn't happen. At MAJCOM we had Xerox machines but the only one you didn't have to get approval was the one we had in the Command Section for our use. Memo's for the Record were not something in those days you could have gotten copied.
