I'm fixing a couple razors for a new member and one of them has the huge pivot hole typical of the old W&Bs. I used to have brass tubing that nested together with the pin but can't find it in my transiently re-arranged basement. Worse, I lost some bookmarks during a computer swap and for speed's sake I'm just asking here.

Can anyone provide me a source and stock number for 1/16" ID brass tubing? I'd also like to get the next size up that would nest with that tubing.
