headlight shell

[ogre]

can anyone tell me what the number should be on my headlight shell 1970 cb750.
cheers

Part number will be 61301-300-010 for CB750 and K1. These numbers could be followed by 2 letters which I guess would relate to the colours. Headlights before K2,s were the same colour as the bike and later bikes had black or chrome coloured headlight shells.

Any use?
