Very rare vintage EMT OFD25 mono cartridge. The cartridge mounted in old style two pin EMT headshell. NEVER USED and comes with the original box. The cartridge will fit older mono Ortofon tonearms and also EMT mono or stereo tonearm. I haven’t tried the cartridge for sound, the coil is OK. The cartridge sold as is with no returns unless not as described. Thanks for looking and good luck.
