Well a while ago, Guenadiy at Accordion Gallery told me hand made reeds may or may not have bluing on the edge of their bases, and in fact may even have machine rivets! I took this with a small grain of salt as I was speaking with someone selling accordions. But I basically believed him. My impression from our conversation, and from testimonials of his customers was that he has solid integrity and knowledge. Today I opened my circa 1960 Excelsior 940 to check the leathers and peering closely at those reed base edges I saw only silver! Well, either my reeds aren't hand made, or the dogma is unreliable! (All reedblocks and body parts are stamped 124 3, and no sign of tampering, so I'm certain this is all original.) Anyways, the old box plays and sounds wonderful (like Jack Emblow's, who if you haven't heard you should check out - I think he is the best jazzer on PA of his era), so I really don't care either way. Just wanted to stir things up.
