Vintage Shure M3D Stereo Cartridge w/ Good Stylus Tested and Working Properly

Description

Another from the cartridge vaults!
The Shure M3D is widely acclaimed as the first stereo cartridge ever made in America!
Legendary and widely coveted, this cartridge is what brought Stereo to the masses way back in 1958, and was made well into the 70s.
This example has been in my possession for over a decade, and just isn't getting the love it should.  The stylus sounds fine, but I have no way to know how many hours it's seen.
Both channels pass signal and sound the same.  It should sound great on a vintage record changer or classic broadcast idler!
Please look at the provided photos and inquire if you require any further detail.
