I have an Austro-Daimler that my wife found at a garage sale. It has a decal that says "Beacon" on the frame. It is made in Austria, has Shimano and SuntourVGTluxe on the gears. The brakes say Weimann & Vainquer. The seat has Schwinn on it. Frame has stamped serial number 5739921.

Is this a good bike, can anyone tell me anything about it? What would it be worth?
