Well, not really sure if this is a definitive answer but I was told this morning that Guilloche is no longer available and that Ruthenium is SO and available if you are lucky.
At the same time I learnt that my dog chewed croc clutch was going to be about £1500 minimum to repair. I had had my run of bad luck so I ordered Kelly 25 Black Evercalf (no chance with box - told to not even ask for it) with 1, Guilloche, 2, Ruthenium and 3, Palladium.
Now the wait begins.......
