@250.00 OBO (as is)
This microphone would make an excellent display piece or put to use and would be sure to attract lots of attention.
I have never used this and I'm unsure whether or not it is in working condition. The end of the cable has been taped with electrical tape, the cable can be replaced. As you can see numbers & initials have been scratched into it.
I suggest you visit the following website to view the manufacturers original data sheet with specifications. It is two pages loaded with invaluable information on the microphone.
