Just because nobody ever puts anything from the UK and they may hold some interest to some...............
Lammers and marker buttons used at "Les A" along with French bet and neighbours markers.
All generic I expect but first time I have seen the lammers from a UK casino. The decimal markers are the type that would have been attached to small hooks although the lammers may have been used in the "trees" where they slot in.

There are also some old roulette balls, maybe some of the smaller ones are ivory but most are either ivorine or plastic I think.
