FWIW, many years ago I acquired a '70s TDF that came with a replacement Tange chrome fork. That fork was fine but I wanted to see if I could make it more 'proper' so inquired at a local SF shop that was a Gitane dealer about ordering a genuine TDF fork.
Back in the early '80s they quoted me $135.
So this one for $65 (in 2025 dollars) is a genuine bargain!
