April's microphone of the month (MOTM) is this glamorous shiny blue ribbon microphone by Framez (not to be confused with Framus!)
This has no model or serial number, but is probably from later 1950s or early 60s. Framez were an Italian brand related to Meazzi - according to one source the name is a contraction of Fratelli Meazzi (trans. Meazzi Brothers), which does sound plausible. Framez / Meazzi also made some cool oddball guitars, and were associated with Wandré Pioli. Fetish guitars have much more information about these guitars.
probably a DIY 'kitchen foil' repair. With a proper 2.5 micrometer ribbon installed, and the mic rewired for balanced, low impedance operation, the sound is clear with a strong output, just lacking a little of the low end proximity boost that you find with many ribbon microphones. The 'low' impedance tap is 1:45 ratio, which gives around a 450 ohm output with the 2.5 micron ribbon.
