What a fabulous idea for Meccano engineers to catch on to -super- efficient steam power to drive off gears, chains and pulleys! Working on methylated spirits and water, the Meccano Steam Engine has a single lever that operates the fy-wheel in forward and reverse directions, and also controls the running speed.
Clean, safe, simple to operate.
