I had them at one point, but fear they are gone about two house moves ago...  omega was the cg, big pin was the pin, and I believe there was a small clear pin (that's the mb).  If I remember correctly, most were drilled with the big pin on the centerline or under the ring and the letter D in the 3 o'clock position.  I think this was supposed to be the strongest.

If you shoot Ebonite an email, they may be able to provide a copy of the drill sheet.
