Antique Scoreboard

[stretch]

I have found this old beaded scoreboard. Can anyone explain anything about it's history and how the scoring system would work. ? https://www.ebay.co.uk/itm/235202816337
Many thanks

Link doesn’t work for me. These old scoreboards are worth a few bob. Don’t like to see them ending up in skips.

Doesn't work for me either.

Here's a screenshot. No numbers on the bottom row. 20250301_204454 by stretch1985, on Flickr

It's a carom (French billiards) board. Start with all beads to the right, then each player records their score by moving beads to the left. The first player to reach 20 wins the frame. The top row is presumably for recording the number of frames?

Thank you for the info, much appreciated.
