That's an old accordion made by "Shine" Mouton.
Probably more than 20 years. Quite possible that it may have Hohnor reeds. I know the stop knobs and keyboard buttons are from Hohnor( that's what was used back then).
It looks like it would need some work to bring it back to playable condition.
That's my take on it.

Yeah, the first thing I noticed was the surface rust on some of the trim. It would really make me suspicious of what condition the inside was in.
Also, since it looks like the seller is a pawn shop, you'd have no idea as to the history of the box. All the same, it might be worth watching, if someone wanted an original Mouton. If no one bids they might entertain a much lower offer.
This has been listed on eBay at least three other times. It started at $699.00 the first time I saw it. It has been listed twice at the current starting price.
