I have a cake slice that is marked on the back S800 wondering if it is a Yogya / Indonesian piece or not and roughly how old it might be, if not, where it is from.
I have added two photos of the mark, one using a flash, one without.
Thanks in advance for any help in identifying the country of origin / age etc.
I have read that page previously, but I am still not 100% sure if this is a Yogya piece or not.
I have had a "niggle" nagging at me, that I have seen this mark before, but for the life of me, I cannot remember if it was a Yogya mark or another country.
