I got some that came on my 57. The overriders are newer looking, the bumpers at one time were "cleaned up" using a sanding disk or something similar so they are a mix of copper, crome and rust. You're welcome to swing by this weekend and check them out, I'm in Fort Langley. If they suit what you want I drink Wisers, you decied on the size of bottle based on what you think of the bumpers.
