Below are some photo's of the traction engine built by my late father.
It's an M.E. 1" scale traction engine designed by Henry Greenly and built by my father in 1946/47. My mother said it took him 18 months. Home from work, dinner then shed. I sometimes wonder how I got born.
I haven't a clue how to run it and if memory serves, it hasn't run for 50 years. It will need pressure testing etc before it does. As to value?
