They do appear to be raschig balls at a glance but I have spoken with a few other collectors the 4 5 15 cue ball spot size weight are all different than your typical raschig sets. I spoke with nihon tamadai the manufacturer who's name is on the case and who sponsored that particular event in Japan. They was kind enough to ask the president of the company if he could provide any information about the set. The case comes from a affiliate in Japan that is no longer in business and identified the set as aramis billiard balls made from a resin that is no longer being used. He described how the balls have a different feel to them and they do. When it comes to specs they are amazing . 2.22525 to 2.22520 and have a total weight variation of 1.4g throughout the set which is very impressive. I have 30 sets that don't compare to them. The set was made to a standard that is unmatched. Because I have never seen a set that matches them exactly i can't say what they are. If the numbers don't match 100 percent they are just not that set. But they are a set a champion would have owned.After Joe passed, a gentleman named Richard Sluzalis helped her sell off Joe's pool and billiard memorabilia. This set of balls appear to be a set of Raschigs. Nice set of balls and a late 60's ball case is a nice touch. I do not think the balls are that old however.

I think its worth noting that the case was Joe's also. My letter of authenticity includes the case.After Joe passed, a gentleman named Richard Sluzalis helped her sell off Joe's pool and billiard memorabilia.

When looking at the set next to examples of aramith sets, I see several similarities as far as color codes and numbers. The 1990 Centennial set in the photo is the 2nd best set i own. Very impressive specs 1.7g of weight variation throughout the set. The set to the left i have not seen a older example with the aramith name attached. When looking at the numbers to compare old sets of balls its important to know the size of the stick. The fonts change accordingly to the size of the stick.After Joe passed, a gentleman named Richard Sluzalis helped her sell off Joe's pool and billiard memorabilia.

When it comes to the age of the balls. The 169.6 gram blue circle cue ball that was sold with the Brunswick Ivorylene pocket balls code number 2-5-5 are close to the same material. The yellowing suggest they are close to the same age also. I do think its possible they are made of raschig resin.After Joe passed, a gentleman named Richard Sluzalis helped her sell off Joe's pool and billiard memorabilia.
