Bryan's description of the layout of Steve's is correct. The one Bryan built for me is different, more chromatic. It also has 5 stops and another set of bass reeds to play in 3rd position. It's #29 on Bryan's L'Anse Grise Accordion web site. I've got a video of Chris Miller playing mine at Augusta, but no idea how to post it here.
These are accordeons made by and for professionals with mitered corners and exquisite workmanship. Less than the price of the average top 3 Louisiana made top three accordeons.
