I think that the two cam shaped bits of hardware may have been left over from when the radio was originally shipped, the base of the radio was probably attached to a board or the bottom of a crate. To me they look kind of like smaller versions of those latches they used to use on wooden sash windows to lock the two sashes together, the cam piece would rotate and feed into a slotted piece of hardware on the other sash.
