Old post, but what the deuce. When I first saw the title "Executive Keyboard," I thought of IBM Executive typewriter keyboards. They are a little different from the regular IBMs, at least here stateside. The 1 and ! key is tucked behind the : and ; on the Models A, B, and C. The Model D looks more like a standard keyboard. I have also seen custom keyboards with the 1 on the upper left hand side. My 1962 IBM has that, although normally the Model C is an 86-character keyboard. This one's an 88. What's more, the 1 is without the !, because the copperplate gothic has two sizes of the 1. Even the numbers are upper and lower case on this machine!
