Got this with a batch of other parts for a project bike. So the bike before I got to use it.

Beautiful chrome-like finish polished show quality only blemish I can see is my own thumbprint

I bought it with a lot of parts that were labeled cb750k so I don't know if there's any differences in years between 70 and 78

Beautiful looking part

If it's really what you're looking for make a reasonable offer and I'll most likely accept it
