Someone before me has already done some work on this microphone as the XLR input is a Neutrik head. It does work, and it is very Lo-Fi.
Reslo-Sound mics were BBC standard in the 40's, 50's so I'm selling as more of a rustic ornament/ collectible. 
The mesh of the microphone is well dented ( PLEASE SEE PHOTOS ) and could use some TLC from someone with know-how. 
Because of the condition of the mesh I'm going to put it a price I feel is more fair than ebay's suggesting, but feel free to make an offer also.
