Early Portable Tape Recorder

[jr_tech]

I ran across this picture on another site...Can anybody here identify the portable recorder that is pictured? I saw one of these once and IIRC, it recorded on 5" reels, was motor driven (not spring wound), equipped with "Cannon" connectors, and was likely powered by wet cells (as the covering on the lower areas of the case was severely damaged, perhaps by acid). The design was primitive, perhaps with no rewind capability. There was a small round plastic "window" on the lid, so that the condition of the reels could be observed.
