Definitely Audio Technica. And definitely Sound Professionals. I'm willing to go with an older version of the SP-CMC-4 (based on the AT853). To know what capsule, you'll need to know the letter or graphic on it (which isn't shown).
I had the SP-CMC-8's (old AT933's) which had that rotating clip shrinkwrapped on the outside so after digging around, I can confirm these are the 4's. Odds are they've never been 4.7k modded so you're gonna run into distortion if you're at a loud show with them.
