The C 1102 was produced by a - so far unknown - OEM Manufacturer in Japan. It had the DNL and the Dolby B System built in. Blaupunkt had a similar unit HC60 that is most probably from the same manufacturer. As far as I could see the motor that the Lenco C 1102 used was a tachometer controlled DC-motor while the Blaupunkt HC60 used an AC-motor directly connected to the primary line circuit.
