Pool Ball Collecting.

They're not a mix set, back in the day I guess they didn't put the line under the six. I've seen it on another ball collector's website the same way. Here's another style of standards. White numbers on the solid balls because black numbers don't show up so well on colors.

And here's a brand new set of crown standards. They have the black numbers on the solid balls because they have the white behind it.

Beautiful, classic sets, HKC.

Thank you for sharing the photographs, dear chap.
