NOS MCM 3 1/2" Racing Megaphone CLAMP w/ CONE ahrma Triumph Norton BSA Honda

Description

You are buying the BARE CLAMP and REVERSE CONE shown in the first photo.  Clamp is new production, cone is NOS original that fits the megaphones shown in the last photos.  Hopefully somebody out there can use them.  You will need your own 10 gauge screw and nut to complete.
These are among the VERY LAST I have...
Suits the BIG MCM megaphones, used to have a pile of them, only a couple left and a few spare parts now.  Overall length about 13", max diameter 3 1/2".
See last photo for what a version looks like, mounted to a BSA B50...
I will answer all questions promptly, thanks for looking.
