Came across this advert for the Prestige gear ensemble from 1963.

Have never before seen a Prestige front mech mounted in this "backwards" configuration as shown in the illustration.

Note also that it appears to lack a travel adjustment screw.

Is anyone familiar with this?

They were typically mounted with the cable pull behind the seat tube; however there may have been some applications where it was mounted as shown. The cage was fixed to a shaft so it was easy to change its configuration to suit the mounting. There should be a small adjustment screw just above the cage shaft (or below the shaft as shown in the above picture). I recall that the adjustment screw only limited the outward movement on the shaft. In other words it was the high limit. I think the low limit was controlled by the position of the cage on the shaft or by the cable tightness. It's been decades since I messed with one.

Simple answer, whoever assembled the derailleur to photograph it put the cage on upside down so the picture is bass ackwards! :thumb:

"Cleverly, the photographer has mounted the body of the front derailleur upside-down - did no one at Simplex do any proof-reading?"

Worked on many hundred of those beasts. The Simplex FD on my all original 1967 PX-10 gave up the ghost a few months back. Miraculously I had a NOS body in my drawer of Simplex derailleurs.

It works reasonably well after some minor modifications to the cage, a new cable and housing plus lots of grease!

Is it wrong... or just French?

Yup, butt backwards alright. The guy or gal probably became the CEO.
