WTB: Bruel & Kjaer Type 4136 1/4-inch microphone along with its UA-0035 thread

[Rob Boudrie]

It would really help my standing at the local gun club if someone has a spare Bruel & Kjaer Type 4136 1/4-inch microphone along with its UA-0035 thread adapter available to supply for a shooting noise project. Cash or trade for a vintage working B&K Type 4427 Environmental Noise Analyzer complete with six rolls of paper. Yeah, I know there are a couple on ebay but they ship from Russia.
