Is it a Ratner after all ? - it’s only the escutcheons which make the link.
It does not look like a Ratner letter lock which had superimposed rings with an operating switch at the centre. Close up photo of the Thai comb.dial attached.
And something I should have mentioned at the outset - concealed hinges. Never known Ratner to use them.
Maybe some Australian connection. Ratners had an office in Melbourne around that time. Maybe had it made locally for the Far East market.
Will try to find out if the safe was ever opened - the answers lie within.
