16 mm wrenches are not real common. I find them unnecessary: 5/8" works just fine; it's within a few thousandths.
call it "Craftsman tolerance" (for our international members, Craftsman tools are the exclusive brand of Sears Roebuck, and pretty decent quality for the price.)

New one on me, I thought all the classic Campy cranks used 15mm head bolts, while Stronglight and Zeus used 16mm and the mid to lower priced Japanese cranks used 14mm. Makes me suspect someone changed the crank bolts. Bolt heads which are not metric or SAE makes one think they might be Whitworth, but I have no idea what Whitworth bolts would be doing on a Campy crank.
