The Ardalanish collection of organic and "ethical" tweeds has a few silver/black combinations.
Apart from the herringbones, these are attractive.
From LL, of course, we have Cooper 1 and Etna HB.
Do check the out of stock list also. A few of the photographed cloths are on that list (and no longer in the physical book). A shame, as I'd been eyeing the grey herringbone with blue stripes for a while.
