If you were to ask Casey Putsch what the difference is in restoring the clockwork mechanism that powers a 19th century French automaton, a military turboshaft engine, or a V-12 supercar he would say, “Nothing”. They all require an intimate understanding of physics and material science, as well as a high degree of craftsmanship, attention to detail, and passion for the art and culture that originally created them. It is nice to have the occasional specification or data point, but the old television comedy line holds a tongue-in-cheek inherent truth that “real men don’t need instructions.”
