Hello!
I created my account here just for this (but I'll stick around to learn, already picking up so much from the guides and a light browse of the forums.)
I apologize for bumping a topic several months old but I must tell you, I have one of these CF Troubadours!
I inherited it from my great grandmother, through my grandfather. I'm not sure if she was the original owner, I'm asking my family for more info. I'm told she could play it like no other, and it looks like she did as mine is definitely well-used. She lived her whole life in a small town in Newfoundland so it would surprise me to learn that it could have been made so far away.
I know nothing about melodeons other than what my last couple of days on YouTube has told me, but I have 20 years of piano experience so I'm getting pretty comfortable playing it quickly.
Mine has the accidentals layout featured on the layouts page.

Hope we can solve the mystery of the Troubadour.
