Meccanograph
Built by Peter Clay in June 2006 for the 1976 Manual Models Secretary’s Challenge
A 1976 № 9 set meccanograph that uses some parts outside of the set plus two 20-tooth pinions. The latter could have been inherited, and the other parts brought as spares which were available in 1976.
Powered by an E15R motor brought with the builder’s first wage packet in 1976!
