Simplex Derailleur Identification
 

Hi: I'm having some trouble in identifying my Simplex derailleur. Can anybody here tell me which model the below derailleur is? My research has led me to the SX-410 or SX-610. Regards.

Moved from Mechanics.

That's a Simplex 410 GT; the 6nn models have a dropped parallelogram like Shimano.

It's also designed for the claw hanger and not easily converted for direct mount with out the unobtainium parts...
