tube microphones...

[Al]

They look a lot like Nevaton's to me...

Nevatons are Russian mics. Google can supply you with plenty of sources, but...

any guesses on from when they were made (look 40s even 30s to me)?

...the page you linked to says:

You are bidding on TWO old german Tube microphones made in the 50 ?s early 60?s. made in germany by REISSMANN EleKTROAKUSTIK in DRESDEN

and what could they have been used for?

Probably just about anything.

and what caracteristics do they have? condenser yes (since the PS). but then what? it's an unbalanced out it has.

They look to be omni-directional. The power supply is more for feeding the tubes.

i haven't tried them out yet, so i don't know how they sound, but damn they look pretty.

Try 'em out and let us know what they sound good on.

Yeah, I'd guess omni directional on the pattern. Capsule looks like a copy of the old CMV-3 from Neumann, and of course, the EF-12 tube is a replacement for the VF-12 tube in a U-47 (if you have the mic modified to accept them).
Unbalanced output isn't too much of a surprise since it looks like the company was mostly a radio manufacturer, and that might have been a mic for hobbyist radio operators? (Just a complete guess right there.)

But I suppose that if you already have the mic, the best thing to do is to turn it on and try it out.
