From the seller

V30 bajonet adapter for Neumann M7 etc.
A very important part that did not came with all of them. For the almost very rare and absolute high-class vintage V30 tube-microphone developed by the RTI germany and W. Franz (later EMT):
---------------------------------------------------------------------------------
Bajonet adapter to use Neumann-Gefell M7, M8, M9 and other bajonet capsules
----------------------------------------------------------------------------------
with this microphone. Handmade from a technician after the original part made by the RTI. Very precise with perfect fit and contact pressure.
Please ask about more info and pricing. More info on V30 and spare parts on request.
Only about ten of these tube-microphone gems exist worldwide.
The sound and built quality is stunning which could lead to the assumption it could have been manufactured by Maihaik.
The V30 was a develelopment of the IRT (Rundfunktechnisches Institut) = Institute for Broadcasting Technology (research centre of the German broadcast), W. Franz, Lahr = former EMT company and Neumann as a further development of the Neumann M1-1 tube bottle mic, similar to CMV 3.
This information is according to copies of the original V30 documentation.
Many thanks to Andreas Grosser.
A different source says that it is (also) a precedessor of the Neumann M50.
Please refer to the V30 omni capsules in the last pictures of this offer here.
