We possess M44E cartridge and the stylus is worn. Also let us know how we can make out if the stylus is used at the time of sale.
The N44-G is the current replacement stylus for the M44E.
A special microscope designed to examine styli is the only way to know if a stylus has been previously used.
To purchase the N44-G directly from Shure, please find the Shure agent in India here: http://www.shure.eu/countries/india
