I know that the "A" nails are available in the City Sofa in the program leather Cavalier Mocha. In the last 5-10 years I have switched the old brass finishes in my home to silver finishes such as nickel and chrome. Are the silver finish nails such as Carpenters and Nickel nails in the same size as the "A" nail also available, and if so, have you ever seen them used on a dark leather like the Cavalier Mocha? The other option I like is the same size Black Pearl. I might actually like that better. Or do you ignore those finishes go with whatever looks best with the leather? My living room is open to the kitchen, and I have silver finishes there.
