An omega with white ensign stamps and the 'A' (alpha) flag flown from a ship or boat when a diver is in the water (in the uk, its different in America) and a cigar 1966 world cup stamps.
Fun you are having Paul are you having the 36 degrees out your way? What material are you using for the clear casting?
It must have been exciting enough to be a diver in the water anyway without confusion of flags.
I had a mate who used to be a salvage diver in New Guinea the local NG Native assistant fell asleep while pumping for him he was down one day and he popped up in a fury. This lad was from the highlands when he got back to the boat he chucked him in the sea as a non swimmer, long story short he then employed two people one from the highlands and one coastal they both mistrusted one another.His contract with t5he Govt was searching for contraband thrown overboard to be retreived by locals.
Whats the next step in stamps mate? There is no end to the possibilities. One with Koi would be brilliant.
Kind regards Peter.
