Without spending a day looking for an old Weiand catalog, W - Weiand, B - Buick, 3 ? should be, or is it a 3 duece? Pulling from memory, what I remember.
Thanks for the help guys, I knew someone on the HAMB would be familar with it. It is a 3 duece, and I was guessing it was for a Buick nailhead. If I don't end up using it, it will be for sale on the HAMB down the road a bit. Al
