I marvel at the several different actions whose operating parameters have been tuned to a high degree of precision in this toy. for anyone who appreciates a fine mechanism here it is. I have received values of pleasure and learning well beyond the small price. I have bought several Sterling engine models over the years and this not only the cheapest, but is the very best one to explain and clearly see the operation.
