Technics EPA 100P - Tonearm


Hey all!
I found this forum and think you can help with advice - I came across a tonearm at the flea market which I understand is the better type.
Since I am not at all in need of such a tone arm, I would be grateful if anyone can advise on its history & perhaps a value before a sale? It is in mint condition and comes from a warehouse to a radio station.

Thank you in advance
Mike
