Here is what I have.
TR KING - Opened in 1924

TR King - USPC made the large crowns for TR King as late 1929, when 9,000 chips were delivered.

TR King - 1st known records of actual chip production is 1936. There are roughly 3,000 records of TR King manufactured chips. I have made an offer to buy the records. Not accepted as of this post.
