I can see something, but it is probably just my imagination.
It is not a cane on its own, but there is something on the edge of one small cane that looks like letters!
As for where it is on the main photo posted above, the (roundel?) canes around the edge of the weight, there is the pink outer canes, then the inner canes, look yellow with a green centre, there is something that resembles letters on the edge of one of those small canes, but it is probably just my imagination! I have tried to photograph it, but it is so tiny my camera (even on macro) cannot get a close up!
BTW I forgot to say thank you for the welcome to the forum earlier.
