Unusual register names on older accordion

[ArtMustel]

Has anyone seen these register names ever? I have not and I'm very curious to find their equivalents (Violino is an easy one of course). Accordion brand is "La Conero, Sirolo Italy" and I've found on the web that La Conero manufactured accordions from 1944 until 1955...

Art,
The designations are in Italian.
Tromba means trumpet, violon- cello is cello, the rest are obvious.
As to what reed combinations they represent, I've no idea?

You are correct Dingo; I've never seen such denomination of voices, I guess one of them is the equivalent of master and maybe another one is clarinet, another one bassoon and yet another one bandoneon, but it is only a guess. It looks like an ancient instrument from when the more current denominations that we know was still not used.

Be a fun quiz to see who can guess what these pre-standardized registers are. I'm curious to hear them now to find out. The dots make so much sense when you know there was no one register-naming system for them to replace.

Every manufacturer used their own imagination to invent names for registers. The result is that names are pretty meaningless. To make matters worse, manufacturers also used their imagination to come up with "nice looking" dot patterns for things like L, M, H... so even when you see a pattern that clearly indicates MMH of instance it can actually be MMM. I have a Crucianelli that is LMMM (and never was anything but LMMM) and it uses register markings that look like that of an LMMH accordion...
So what you need to know is learn which register button opens which sliders, thus activating which reed bank, and memorize it so that you can ignore what the register button says. On my Russian bayan I have 8 chin switches which are all nice evenly black buttons (accordion buttons actually) without any marking on them. Had to look at a chart a few times during the first week, never again after that.
About the posted picture, I would not be surprised if the registers were from left to right: L, LM, LMM, MM, M. Never mind what's written on the switches.
