Almost certainly BBb. The tubing is too long for Eb, and I don't think that they made these in C.

Most likely a BBb tuba.

BBb fer sure.

Any way to tell what key this is in just by looking at it?

Looks like an Olds O-99/Reynolds TB-10 which Bach marketed as a Mercedes for a while. It's a nice tuba, though small. Definitely a BBb.
