I recently found this old looking Mahjong set, and I was wondering

well, the tiles are numbered, so it's made for western players.

perhaps this helps:

It has Singaporean flower tiles, so it might be from Singapore. Also it uses the old-style Wan symbol so it's probably from the 30s at the latest, but could be older. I would guess younger than older because of how good conditioned the tiles are.

It's hard to tell what they're made of with just those pictures, could you do some close up ones and also show the sides/backs? If they are all made of one solid piece of material or whether they are made of two pieces will be helpful.
