[CR] [CR} WTB Late 70's early 80's Huret front derailleur

I'm looking for a late 70's early 80's Huret front derailleur for a mid 70's French bike I'm building up. It's going to be a rider so I don't need any collecter's items.

I want a derailleur that's somewhat period correct to go with a Huret Challenger or Success RD. No Jubilees or Alvits need apply.

There's several currently on eBay but they're not what I'm looking for.

A Huret Challenger like this would be great:

Also a later Sachs-Huret like this one:

No visible rust please on the outer cage or top front please.
