I found this on ebay last week.
I've never removed the steering column cover to check properly. But the horn button/turn signal stalk thing on my '72 looks like a Lucas unit.
The part that's normally visible (stalk and horn push) looks identical to the one in my Sunbeam Rapier.
The one on ebay has gone (or at least I can't find it).
I've probably got a few of the Lucas ones in my stash of Sunbeam spares.
If you can't find anything in the US let me know and I'll check what I have.
