The device roughly in the middle looks like an aftermarket antenna transformer since it has two lead connected between the antenna connection and chassis ground. I don't know what that bat switch may be for but it looks like it may be audio related, treble or bass, those are the sorts of things I remove when I find them, along with phono jacks, as they usually cause more trouble then they are worth.
