David.. this might seem a bit strange, but I’m in the process of kicking the bucket myself. Selling off watches, collectibles,audiophile parts etc. I know that my parents have No clue what is what. What I want to say is..(I don’t know the degree of nerdyness you got in this hobby). If the inheritancea are unclear What is genuine, what is ”aftermarket” and help with valuation I’ll gladly help. Who knows, those funds could help a local charity or something.. I’m just expressing my thoughts, that swirl around. P.S. Don’t wait to long with help, at least from my part as I might have started the real journey by then.
