How did they work without cogs on the jockey wheels?

Not really a problem surprisingly -the chain tends to stay put.

Historical piece no doubt but my god I'd feel a fool spending that much on an inefficient shifting system.

Anyone know anything at all about this mech?

It appears that the seller started a similar thread in january.

any info on SIMPLEX Gran Sport rear derailleur?

Hi I just bough this piece because I was curious and to lear a little bit about, as I've never seen this Simplex derailleur but also cound't find any info on the net or in any catalog. Looks pretty similar to Record first type from late 50's and early 60's. Does anyone have any clue about it...
