Very interesting read (Love’s: A Century of One Family’s Enterprise). After reading this booklet (and a little more research), I have a rough idea of the time period of use for each of the  M&R “2TB-XX”tokens.

As an example, Silva’s Bakery (2TB-20) is identified in this 1910 newspaper (and they got a bad review).

Love’s Bakery was the 5th bakery in Hawaii.

The first commercial bakery in the islands was operated by Ah Mow (Chinese baker).
