I know much has been said and prehaps Boris and TN can catch us up with what has been said if so desired.
What that means is I’m not getting up off my couch to pull it all back.
As a watch repairer, it has become second nature or it always was.. I see what I see of what is thrown away and as long as I remember which box I threw it in, I can always come across something/sometime/somewhere, recall of pattern can allow me to quote a customer that I can fix this becuse you threw the part required away on such and such a day and I still have it here..
