I guess this thread comes closest to what I'm looking for.

I found an old pitch pipe. Looks like a lipstick tube, about 2" long. A silver case, and inside is the pipe. It has several sleeves of brass inside and you turn the middle of the tube to create openings, air vents. Blow into the end to get a harmonica-like sound. An arrow on the side of the turning sleeve points to C, Cis, D, Dis and so on. Writing stamped on the sides says "Dur," "Moll," "A-440," and "Germany." In great shape, sounds good.

Does anyone know what this kind of pitch pipe is called? Any history on it?

Thanks.

Also, how do I find out which handles are being used by members here? Is SongWronger being used?
