Thanks, Ned. Actually, it was your Video Challenge that inspired me to create the YouTube advertisement for that accordion. My demos are a bit clumsy, I'm afraid -- partially because I haven't played that box for quite a while, but mostly because I'm still very much a beginner on the instrument.
What I am selling is a Dove Cajun accordion in the key of C, handmade in the 1980s (and later refurbished) by Mr. Rufus Foreman of Sunset, Louisiana. It's not a Savoy or a Martin or a Poullard, but it's a nice starter LA box (and better than the Chinese alternatives) if you're not quite ready to invest $2500+ in one of those. I bought this second hand in late 2015 (having caught the bug at Festivals Acadiens), and after playing with it for 3 months I was committed enough to buy an Acadian.
Asking price is $600 + shipping - same as what I paid for it.
Feel free to message me for more info. Lots of pics available and I'm happy to answer any questions.
Just wish I could figure out how to embed the YouTube here. I'm using the old BB code approach (the word "youtube" in brackets surrounding the URL), and the YouTube box shows up fine but won't link to the actual YouTube video.
I had the youtube and brackets part right, but the form of the URL you provided is very specific, and is slightly different both from what shows up in the address bar in my browser as well as from what YouTube provides (under "Share") as the weblink.
