Some call these sets that. I call them "luggage-style" portables. In the pre-war years these sets had nice big chassis' and very often tweed cloth covering with multi-colored or brown stripes. Those are my favorites. The post-war models often had wimpier chassis' and non-striped tolex covering. This 1939 Motorola 41D has an unusual dial. Off, you see a decorative "Batteries Off" plate. When you turn it on that plate swiftly springs to the left revealing the numbered dial plate behind it. Someone killed all 4 tubes sometime in it's past, but with the help of a friend and modern batteries it lives again! It's one of the best playing battery-only portables I've ever heard too. Very sensitive with plenty of volume.
