Funny that Brunswick had a table termed the "Union League". Many years ago while working in NYC on Park Avenue south of Grand Central ; I wandered into the "Union League" private club near 37 street and Park Avenue. It was a very old institutional club- political in nature, I believe, and they had a full billiard room with several tables.
I cannot exactly remember the style of tables, but, perhaps these were the tables in that large billiard room. The NY Athletic Club overlooking Central Park in NYC also had a very large Muti- table billiard room the looked just like a 1930s billiard hall- old style Billard chairs, wall racks, lights, etc. etc. with the straight pool scoring beads on wire throughout.
