This chip is Seymour coded PS-TT. At present I don't have a name for the Billiards Hall. However I have about everything else. The writeup on my website is here:

I recently made a VERY large purchase of c&s. It so happens that there were two of these, never before seen, chips. Anyone have a great trade for me? There are only two known chips, both red.
