I was working on a mid 1980s Pinarello with a Campy Super Record groupset and the Campy engraved crank bolt is 14.5 mm. I have never seen anything other than 14 mm and I was wondering if anyone remembers this setup. Also, where in blazes do I find a wrench?

Take the frame to your friendly hardware store and see if you can find a socket which fits. My guess is for $3-6 you will find a socket that fits. ACE brand sockets are thin enough to fit in my Campy cranks.
Campy used a 15mm. The Japanese used 14mm, French used 16 or 17mm. A 9/16 wrench is almost a perfect substitute for a 14mm wrench. I went out to buy one of those wrenches park used to sell with 14/15/17, and found out that nobody sells those wrenches around here, if they exist at all. You need a thinwall 15. I don't know if Sears will still honor their lifetime guarantee when you break one of their sockets after you grind it down; they used to back when they were still run by people that knew what a good marketing ploy that was.
Thanks guys. The size of the bolt is about .35mm smaller than the usual 15mm bolt heads I have measured, but I will look for a thin 15mm socket. Glad they went to 14mm finally.
I just solved the same problem (15mm crank bolt of an 70's Ofmega, Campagnolo clone) with a Craftsman 15mm 3/8 socket bought for $3.90 at Sears. The socket is 21.5mm in diameter that fit perfectly into the 21.8mm opening.
I saw that in the 1986 catalog and assumed it was the right fit, but I was not about to throw $40 on an assumption if it turned out that it was not for the exact bolt I had. I'll go with the thin wall route.
