This is where SRAM came from as they are a conglomerate of Huret, Sachs, and other European manafacturers that were failing.
The Prestige gets better when you replace the jockey wheels with Suntours which are nearly indestructible... having the jockey wheel crack / break on a Prestige was never a good thing... and I really like how well they shift which is something Simplex usually got right.
The JUY 543 on my 1957 Peugeot shifts like it is indexed although these were never under-rated... they were some top end kit and Campagnolo's new parallelogram derailleurs did not compare to these for some years.
I would agree if you can find an old prestige in good shape and replace the pulleys jockey wheels with Suntours you will have youself a very nice dr I typically sell rebuilt prestiges with suntour pulley's for $30-40 fairly easy.
