I picked these up a a great antique show in Brimfield, MA. First time at the show. It must have 5,000 dealers.
Here is the info I received from the dealer who seemed quite knowledgable about Sarstoga clubs. The intertwined BC is from the Brook Club and is in Ed Hertel's book.The "Brook Club", yellow, red and green are the same on both sides. They have the hrtrct mold and are not in Ed's book. The "B", with the rct mold is also from the Brook Club.
GEK is from Newman's Lake House and stands for Gerald E. King who owned both Newman's and Riley's Lake House. All are in Ed's book. Not in Ed's book are the brown and white NLH which is also from Newman's Lake House. These are the same on both sides.
PRC is the Piping Rock Club. The yellow has no denomination while the brown is $5.00 and the green, $25.00.
SWM is Smith's Interlaken. SWM is for "Scotchy" William Morrison.
The last one, GWC is from a club called the Arrowhead. That's all the dealer knew, but he will try to get more info and let me know.
I do have some extras of all of the Brook Club, except the "B" chip, GEK brown and white, NLH,PRC and SWM. I also have a few $1 PJS Table Two (Riley's Lake House).If anyone is interested, I will sell them for $20 eqach, except for the PJS which is $10. Price includes postage and there are only a few available on a first come basis.
