Paul-Son went into business in 1963 but they did not make their own chips until the late 70's, possibly 1979. I know you must have H/C chips from these years. Guess what? They were made in Portland Ma at the Burt Co. Paul-Son Roulettes were still being made in Maine right up to the early 90's.

Bud Jones went into business in 1965. Their clay chips (not the coin inlay) were also made at Burt Co well into the 70's.

John Kendall, owner of Chipco and buyer of the Burt Co, gave me this information from memory so the years could be off a little but not much.
