I wouldn't blame the author, since I've read about it in other older sources. I'm pretty sure the source of this other board or commission is law enforcement during the 1930's thru 1940's. These men were observed by FBN agents meeting in the NJ area. Phrases like the Big 6, Big 8 (not to be confused with the Big 7 AC conference) or the syndicate were probably coined by local tabloids.

Mulberry may be right in that they met for financial gain and was not an actual commission. For the most part it looks like nothing more than Luciano/Lansky's top associates during that period.
