I have a single speed and an old Schwinn ten-speed.
I really want do a fixed build though, so this frame is no good for me.
As for brand it's a Decathlon. Never heard of it before, but then I'm not some bike company trivia nut.
It looks to be in pretty good shape, not even a scratch on it, much less any signs of major damage.
I'm thinking I'll just get rid of it and find a better frame, I might even be able to come out of it ahead if I can get someone to buy it.
