Hard to see from the photo but the Retro would appear to bear more than a passing resemblance to the Typhoon twin....?..........what DID happen to Typhoon anyway 'Minaatur Modellmotoren' or whatever they called themselves-they produced some good racing engines-2.5cc, 5cc diesel and glow in the 50s...plus the twin of course.
