I have this accordion and I have no idea what it is

Sébastien Consiglio was (or perhaps is) a musician. https://www.youtube.com/channel/UCFrqyvqF3G5ybF_mXmPkAKQ/featured

I don't know who made this instrument, or whether it belonged to Consiglio himself or was just using his name as an endorsement. To me it looks like a Dallapé. It has every sign of being an excellent instrument, whoever made it. I'm assuming it has 4 voices (LMMH) in the right hand and 5 bass voices. I suggest bringing it to an expert. You can also post pictures of the interior here, if you're comfortable opening it.

If that's not made by Dallapé I will be astonished. Pure class.

 

[Ventura]

well, don't forget that the companies of the original Co-Operitiva built a lot of
look-alike models, as several principals came from the Stradella area with
some tooling and a few boxes of extra shifts and stuff

If you are able- some pix of the inside would be nice too. Looks like it could be a real nice instrument.

Yes the bass & treble shift machines look like original Dallape . Good guess.
