More pics of this radio from the backside, which as seen in pic 1 actually hinges open with a couple of knurled screws in order to change batteries or whatever. Pics 2 & 3 are a little (usually covered by a sliding cover) panel on its back allowing access to several additional controls, audio or antenna connections without fully opening the back -- frankly I'd never noticed that little panel was even there until taking these pics today. Pic 4 shows about the only remaining labels of any sort within it, most of those appearing to be factory inspection and/or part/assembly labels -- nothing else whatsoever to provide further details of its maker, date, or any more of an exact model number.
