Greetings,

I was looking around in the boneyard for a rear derailleur and found this one: a TECH 500. I have never heard of this derailleur and web searches came up empty except for one passing BF reference on a 2013 post. To me, it appears to be at the lower end of the RD spectrum. Being a curious type I thought I'd ask if anyone here knows anything about this brand.

The bike is a late 70's Kent Diplomat with a 14-28T 5spd Falcon Freewheel.

Many thanks!
