If I decide to sell my Sidney Brown accordion, would anyone be interested? Just so you'll know, I consider it a collector's item. Marc Savoy says Sidney was the first Cajun Accordion maker. I've done a limited amount of research as it takes time, but Junior Martin repaired one key pad so he's seen the inside. He tells me it's in the key of F. I will respond to all who are interested. You can find pictures of this instrument in this site. Consider this a pre-ebay offer.
