HEADLAMP ASSEMBLY, MCH 66 .
Lucas MCH 66 headlamp shell/assembly from the mid-1960s electrical equipment lineup, PN 58395.
This is the Lucas headlamp shell listed in the catalog as MCH 66, the bowl that houses the headlamp unit up front on the bike. It shows up in the electrical equipment figures alongside the ignition coils, wiring harness, and direct lighting components, which tells you this is part of the front lighting circuit rather than anything magneto or battery specific by itself.

The catalog record ties this PN to appearances from 1963 through 1966, so it belongs to that mid-60s window of production. If you're trying to match up an original headlamp shell for a bike from that era, this is the number to look for, but confirm against your own parts book since the catalog doesn't spell out which specific models used it.
We don't have more detail on this one beyond the figure placement and years of use. Call the shop and we'll help confirm fitment before you order.
