He is now late 70's-early 80's and I haven't seen him out since I started playing again. Johnny Jacket (Jackowisz, IIRC) is his name. He was a good player in his day, Howard Vickery among others played in a weekly ring game with him and Johnny usually got the money (Howard told me that himself). So Given his age and the fact that he was a good player, I have no doubt what he said was true.
How did the person that wrote the Wiki article come up with 5-1/2" pockets?
Here is a snippet of the onepocket.org interview with George Rood and I think that you know that George knows what he is talking about when it comes to that room and that table....
1P: When you said Springfield, Ohio, I thought that sounded familiar. So that was where he ran 526?
GR: That's right. That was in the room that I owned, but I didn't own it then; I bought it later. It was the same room where we had played our exhibition, but it was after that, at another exhibition, when he ran all those balls.
1P: Was that same table where he had that run still there when you bought the room?
GR: Yes it was.
1P: I'm told that was a four by eight table?
GR: You're right. Now, we had played on a four and a half by nine, but it was a four by eight that he played on, with another fellow, on the night he had that high run.
1P: George, do you remember how tight the pockets were on that table?
GR: They were large.
