This was given to me by a friend. They were left by her deceased husband and his children did not want them. I'm hoping the price tags might narrow down their date. Price on the pen is $17.75, and the pencil is $6.50.
Both were in cellophane slip cases when I received them, and the accompanying paper seems to indicate they were refurbished in 1974. There was no ink in the pen so I assume it was never used after Sheaffer sent it back to him.
