My collection started about 2 years ago, and I bought some special sets already like Poker Balls, Bocette, or different styled Chinese ball sets. I don’t know if any of them are worth posting here. But I have a few strange sets/balls I acquired over the last year. First of all, this small carambolage set. Does anybody know what they are used for, or what table size?

And speaking of carambolage balls,I have a few single balls from buying lots. But these vary in size by a bit (maybe 1-2mm). Are these different balls for different games, or maybe just manufacturing and tollerance differences?
And I bought a set of these unnumbered 9-Balls. The webshop showed them in a green Aramith box, but I received this black one. As it looks like all the Chinese boxes, I am not sure what I actually got there now
Another set I got, are these Crystalate Snooker balls, but the set is not complete. I think the set should be 48mm, which the reds are. But I am missing the blue ball, and all colors are smaller, maybe 45mm. I didn’t even know, they made Snooker sets this small
I hope thats good enough for a starter in here
Oh and I would have a question as well, although I posted already in a seperate topic. As it seems, that the Aramith Harlequin balls are no longer under any trademark or anything, and not really anywhere to get as well. Is it ok to ask for, and might anyone be kind enough to provide me the rules for the games they came with? Maybe as scan or pictures. I would like to try these games out as well, and as they are only colored balls, I may easily replace them anyway…
