It's probably a CMI bass - the C looks like part of the M if you've not seen the logo before.
Google "CMI Jazz Bass" & see if the pictures are the same as the one you're asking about.

Not many pics out there but logo seems to match that of CMI right enough. Ive asked for some pics but it does look like an accurate copy. Wonder if it was made in the 1970's?
