Stuart high speed engines part 1

This is a pile of stuart enclosed crank high speed engines. Made either just before or just after the 1st war. To the right of the three MTB1b engines is a sadly chopped up Star, which was the replacement for the aluminium MTB1a. It came out in the mid thirties and disappeared around WW2.

This big green meanie is the MTB3, its over 8 inches long and 4 wide. Weighs about 5.5 pounds and will drive a 150 watt dynamo. Replaced by the stuart Sirius, i think this one may well be one of the most attractive stuart engines.
