Have you ever heard of Hiduminium? The G.B Coureur brake callipers are made from it. I suppose it’s a type of aluminium. It’s very lightweight, like almost everything on this bike.
Enjoy the very vintage Chater-Lea, Le Simplex, Super Hold, Brooks and G.B Coureur parts.

Yes, it’s an aluminum alloy: https://en.wikipedia.org/wiki/Hiduminium
Looking good so far! It’s satisfying to see how this stuff cleans up.
Are those brake calipers before and after? They look good. What did you use to clean them?
