UNKNOWN PHILIPS MICROPHONE.

Below are photos of a Philips microphone believed to have been on the market in the early 1930's. However I have not seen any information on it in any documents.

If you have any information on this mike I would much appreciate hearing from you.

The microphone is black bakelite in a metal frame. The frame is painted gold (it has faded) It is supported by 3 coil springs. The outer frame is reminiscent of some 1920's Philips speakers.
A rear view of the mike. Several Philips speakers from 1928 - 1931 had seven sides, eg. the "Sevenette" speaker. This microphone seems to be from that era. The first photo on a white background is close to true colour. The other two suffer from poor colour rendition - I blame the camera, not the operator.

The rear with the Philips logo unscrews to access the microphone insert. The insert seems to be a Siemens Halske type HO. It also appears to have lettering "ZO5" and "F. mph. 36"  printed on the insert case.
