I only ask that you settle up payment immediately after the listing closes. Here's an early, open-mounted wireless receiving set manufactured by inventor and entrepreneur A.C. Gilbert of New Haven, Connecticut. It uses a single tube for a detector, a rheostat to control the tube's filament voltage, and a primitive loose coupler -- in conjunction with a pair of variable condensers -- for tuning. It's a scarce, unusual radio. Designed by radio pioneer Clarence Tuska, who at the time was struggling to get his own fledgling wireless company off the ground, it was based on a Murdock radio circuit that dated back to the early teens, and it bore little if any resemblance to the simple, box-shaped radios that Tuska had designed for Gilbert just a year or two earlier. If I'm not mistaken the radio was never marketed by Tuska, only by Gilbert, who grouped it with his other wireless offerings in the 1922 Gilbert Year Book.Condition of the radio is very good throughout. This was an inexpensively manufactured set -- built to a price rather than a standard -- and the few surviving examples typically come in just two flavors: either 1) restored or 2) trashed. This example is, thankfully, neither. It's in very nice original shape, as you can see in the photos, with a good original undamaged board whose finish is weathered but still intact. Wiring on the underside of the board is original and in excellent condition. All of the electrical components are original, still functional and relatively clean. The small hardware is solid brass, with no nickel plating, so there's tarnish on the binding post nuts and tube contacts, but nothing bad. Variable tuning slides easily along the rail, and the original wiring -- with the correct green silk sheathing -- is still tightly wrapped around both tuning forms. The knurled bakelite knob on the end of the variable tuning coil is a period correct replacement. Everything else on the radio -- including all of the small screws, contacts, dials, etc -- is original. Original A.C. Gilbert tag is still in place on the top side of the board.Overall, a nice and remarkably original example of a radio that seldom turns up and is sought after by both early radio enthusiasts and Gilbert collectors.The receiver measures approximately 15" x 9" x 6".
