Excellent condition. Looks and sounds fantastic and the case is in great condition.

From Wikipedia:

The D-22 and D-33 were introduced as part of the full-vision (FV) series of microphones in the early 1950s. Its major innovation was its slim profile. Other microphones were typically large and bulky. This blocked the view of the presenter on TV.[1]

The sleek design was achieved with a precision machined "Duraluminum" case with a two-tone color scheme.

The D-22 and D-33 featured a micro-metal alloy diaphragms which was unaffected by temperature changes. The diaphragm also had an anti-corrosion treatment to protect it from air born contamination from the presenters voice.

The D-22 and D-33 were dual impedance microphones with the high/low impedance selected using an innovative "linkage bar" under the name plate and a unique "slide-lock" microphone stand mount.[1]
