Ortofon Fine Line Cartridges OM30 vs 2M Bronze

Although the OM30 was released 23 years before the 2M Bronze, the two cartridges are almost identical.  The stylus assembly components are the same and the main dfference in the cartridge body is the coil design.  The 2M Bronze has silver plated copper coils while the OM30 has standard copper wire coils.  Otherwise, the specifications are very similar.  Remove the mounting shells that surround the cartridge bodies and it will be difficult to tell them apart.
