Offered is one Western Electric 618B Dynamic Vinatge Microphone. This is the only "B" version of the 618 that I have seen or heard of. I cannot find any information about the "B" although it seems identical to the "A" which is quite rare but more familiar. This was purchased from Japan althought the lettering on the back appears to be Chinese. The 618 is of historical note as it was apparently the world's first commercially available dynamic microphone. ("Twelve Microphones that Changed History") It was heavily used in radio at the time, indeed FDR is pictured behind a bunch of these during his fireside chats.
The function could not be assessed as I do not have the No. 80A amplifier nor do I have cabling. The condition of the mike is excellent and it comes in its original wooden, felt lined case. The case is missing the handle. The product information can be reviewed here. The 618 was developed at Bell Labs in the late 1920s by Wente and Thuras, with a patent following in 1931. Bell Labs was the research/engineering branch of Western Electric at the time. It was actually a unidrectional dynamic mic with low impedence and high sensitivity.
