The Audio Technica ATM31r was an update of the AT813 aimed at the professional market. Unlike the AT813, which only runs on batteries, the ATM31r only runs on phantom power.

Preservation audio did a nice write up on the AT813 comparing them to a Neumann u87. Unfair comparison? For what it's worth in blind testing my girlfriend chose the AT813 every time. The audio comparison can be found here: http://www.preservationsound.com/?p=5927

This mic is in outstanding physical condition and perfect operating condition.

Comes with a new generic alligator clamp style mic clip.

Really nice sounding vintage Japanese mic great condition. Sounds amazing.

This is a recording of the actual mic for sale:
