Ariel Arrow?

[ramwing7]

I've pulled the wiring loom from my 1962 Ariel Arrow and am finding all sorts of interesting mysteries.  The current on is a "what's this".  Pictured below is what I'm thinking is some sort of rectifier.  I've never seen something like this, but it doesn't have anything else I would call a rectifier.
Anybody have any opinions?
Thanks.

Yes, it looks like a rectifier.

Not only does it look like a rectifier, you can actually see the 4 individual diodes
that make up the diode bridge.

And potentially replace one if it goes bad.
Dunno about that R1 .....

Looks like someone's scratch built rectifier, good effort but easier nowadays to to buy a standard bridge rectifier.

Thanks folks.  This bike is proving to be full of "creativity".
A modern one is already on order.
