(with Radio Corporation of America of Camden, New Jersey, as contractor) for the Navy Department, Bureau of Ships.\u003c\/p\u003e\n\u003cp\u003eIt is rated at 400 watts maximum, 13.3 volts DC, 30 amps, at 4,200 RPM. The data plate indicates it is “FOR USE WITH MODEL MAR\/RDR RADIO EQUIPMENT.” The engine is a Lauson (The Lauson Company, New Holstein, Wisconsin) unit with manufacturer’s serial number 7-57582 (and generator serial 1412 on the example shown). It includes a carrying case\/cover marked “THIS END TO FACE CARRYING CASE COVER,” rope-start (with wooden handle), fuel tank, controls for radio\/battery charge, automatic voltage regulator, and detailed operating\/lubrication instructions on the engine plate (Navy Symbol oils, high-octane or regular gasoline, etc.).\u003c\/p\u003e\n\u003cp\u003eHistory:\u003c\/p\u003e\n\u003cp\u003eThese compact sets were built during World War II to supply DC power for Navy radio equipment, specifically the MAR\/RDR series. The MAR was a UHF transceiver (transmitter-receiver) used for line-of-sight voice and code communications; the associated RDR was the companion receiver. The generator could power the radios directly or charge batteries.\u003c\/p\u003e\n\u003cp\u003eLauson (a Wisconsin engine maker known for small industrial, marine, and later aluminum military engines) supplied the lightweight, often aluminum-block powerplants for such portable military gear to reduce weight for field\/shipboard\/amphibious use. Atlas Aircraft Products handled the generator end. Similar Lauson-powered Navy radio generators appear in period documentation and collector discussions (e.g., Smokstak forums), confirming their role in supporting portable and transportable Navy\/Marine communications sets of the era.\u003c\/p\u003e\n\u003cp\u003eThe overall design is typical of wartime “power units” for radio: rugged olive-drab finish, sealed features for transport, rope start, and dual radio\/battery-charge switching. They were part of the broader effort to equip ships, shore stations, and mobile units with reliable portable power independent of ship’s mains or large generators.\u003c\/p\u003e","brand":"Whiskey Rebellion Antiques","offers":[{"title":"Default Title","offer_id":43358289887309,"sku":null,"price":525.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0610\/9229\/8829\/files\/rn-image_picker_lib_temp_f8e4932a-6159-400c-ba76-bb93a80b7304.jpg?v=1785778980","url":"https:\/\/whiskeyrebellionantiques.com\/products\/type-ccw-73037-portable-generator","provider":"Whiskey Rebellion Antiques","version":"1.0","type":"link"}
