This is a rare quack medicine device, made of tokens, a couple of beads and wire, incidentally Rulau wrote about it somewhere not sure where as I have it on a word document, I'll place it below. Anyways, I occasionally see one token on the bay but not the complete quack medicine device as it's rare, just sharing and if you have a quack medicine device to post about, here's your opportunity. Rulau notes that only two complete puzzles are known! J. Garst was the proprietor of Phenyo Caffein Co., a medicine manufacturer. Two trade tokens from this issuer form parts of this rare puzzle, Ma-WC 12 and 13. Both tokens are uniface brass discs at the end of a complicated assembly of wire loops, rings and wooden beads. One token gives instructions on how to work the puzzle, and the other is an advertisement for a caffein remedy: CHILIAN PUZZLE / REMOVE / THE RING / AND / PUT IT ON / AGAIN, and PHENYO CAFFEIN / CURES / HEADACHE / AND / NEURALGIA /PHENYO C. CO. / WORCESTER / MASS.
