Jeff, you're right about Castagnari which is beautifull built, but the reeds are all standing up :blush:
My Falcon has also mitered corners and Rusty Sanner built also accordions with mitered corners because he learned a lot from the late Mr Randy Falcon.
Even my leak old Hohner in low G has mitered corners.
For me it's not a big deal, because I play my Martins Juniors with the same pleasure as the Falcon or the Castagnari :blush:
The Savoys and Millers I was obliged to play on , are also very fine instruments :blush:
Maybe it's time for The Mitered Corner Two Step :joy: :joy: :joy:
