Does it need to be indexed? I've got a Simplex SX630 long cage which although the steel pulley arms are tarnished somewhat (Not rusty) it works perfectly, not been tried out on indexed system though so couldn't say for sure. (There's a reference on Velobase of someone doing it however with Sachs Huret Rival 8 speed shifters)
£20 including postage (not London based..sorry)
