Span looks like about 4 3/4, maybe 5. 1/4 quarter reverse. I don't know much about ball drilling, so I may sound like an idiot, but I'll try to give more info. The big white dot (PIN??) is straight up and a little to the right of the right fingertip, probably an inch and a half up from the fingertip and 1/8 inch right. That's about all. Thanks for the response,
