Kawasaki 250 350 500 F5 H1 A1 A7 F7 Mach III Avenger Samurai Gas Tank Fuel Cap

Description

Original cap from an early 500 triple as far as we know, but fits a wide number of late 60s models with twist-on caps.
I cleaned up some surface rust underneath, but top side looks pretty nice. There's a slight dimple in the top but I think that's how they look.
Will need a new gasket.
