IIRC, those symbols typically mean 'The low reeds + the non-cassotto middle reeds' and 'The non-cassotto middle reeds + the high reeds'. On all the other registers, if only one middle dot is shown, it implies its using the middle reed block that's mounted to the tone chamber.
In other words, your accordion probably has the low reed block and one of the two middle reed blocks on the tone chamber. For all registers except the last two, if one middle reed block is used, it's the one on the tone chamber.
Jim, are you confirming that (a) there is no cassotto and (b) the symbol refers to "low reeds plus detuned middle reeds" and "detuned middle reeds plus high reeds"? Are there any references to this online (manuals?, these symbols being used elsewhere?)?Your guess was right on Dingo !!!
Generally, Paolo Soprani uses “Super Paolo” to identify their models with cassotto, so I would think that this accordion does have a cassotto.Jim, are you confirming that (a) there is no cassotto and (b) the symbol refers to "low reeds plus detuned middle reeds" and "detuned middle reeds plus high reeds"?

The description on Reddit implies that this is an accordion with a single tone chamber. I was under the impression that single chamber accordions generally had only the bassoon (16’) reed set in the chamber. If this is true, then the symbol does not seem to refer to the cassotto since it is not shown as applying to the 16’ reed bank only but seems more closely associated with the 8’ reed bank.I can confirm that it is a Super Paolo. The good folks at reddit have been very helpful as well, but it is fascinating to see that no one appears to have first-hand experience with these symbols. Considering that it is a Super Paolo, my best hypothesis at this point is that the symbols indicate that the middle reed used is not the one "in the cabin", i.e. Cassotto. It's also my favourite hypothesis, as I want to own a Cassotto accordion. The Paolo accordion is heavy compared to my Hohner full size accordion, which confirms the hypothesis, and so does a (very much non-expert) sound comparison between the different switches.

Mine does have a double cassotto and it has no markings. But mine is not a double octave accordionScuromondo, does your Super Paolo have a Cassotto? Do you have strange symbols on your registers?
Thank you, Gonk, for all your help! I am still somewhat unsure if we've come to a definitive conclusion. I just looked up super paolo soprani with cassotto on ebay, and I could find no other accordion with these symbols.
