I have been looking into these chips off and on for about 2 months ( not spending a great deal of time).
We know the hubs were sent to...

Pasquale Maiocco (Dante Billiard Parlor)
536 Broadway
San Francisco 1936
** there were 2 more small orders in 1937**

1928 Polk listing

1948 This guy moved around a bit.
Not sure when the "L" mold chips were ordered. My guess would be 1950+. Almost all of these chips are very worn except the pink "L" molds.
I welcome anyone else with info to post here and anyone else willing to look into this place to add any input.
