And your picture archive never seizes to amaze - watch boutique on cruise ship, check, Rolex customer correspondence from the 1940s, check 
Wanted to pick up on another point you, and several others raised, namely the connection to mechanical objects and the sensitivity to fine things. I feel that the mechanical connection is becoming less prevalent than it used to be. Many household appliances that used to be maintained and repaired in the past are now throwaway objects. Same with cars - the mechanical sympathy and basic understanding of the functioning that was required in the past is often completely missing nowadays. While I have neither an engineering background nor a mechanic's education, I can still diagnose some basic problems and fix the handful that are still fixable on modern cars (less each generation). If I compare that to many of my generation, I actually feel privileged. One can only hope that all the IT / electrical engineers develop an interest in mechanical objects as a hobby 
The question is whether the sensitivity to fine objects is a constant in society or not. While I do not doubt the effectiveness of the forum members here as fine teachers, will they encounter an equally receptive audience, as in the past and will it be sufficiently large?
Questions, questions...
But in any case thanks for the time taken and the thoughtfulness of your response - at least you (and most others here) have some answers, too
