Vintage AKG C414 microphones tech info needed

[magickalpig]

Hello,

I'm listing a couple of mics to sell in another forum (FStherstuff) and I'm trying to find out any technical/historical info that might help potential traders/buyers

Microphones are AKG C414 NR 2490 and NR1408 both have brass capsules but I can't say with any certainty if they are C12's I think they are as they sound great but I don't know if I want to take them apart to prove it or if even taking them apart would confirm it.

Any and all info is appreciated.

Thanks,

Terry

Try asking over here if you don't get any other response on TB:

I'm sure someone over there will be able to give you some background on them... might be a another good place to unload them as well.
