Treble registration symbols

[wirralaccordion]

The dots can be listed in one, two or three rows and there can be one, two or three dots in each row. This makes for a large number of possibilities although there are usually a maximum of say 11 combinations/registrations per accordion.
Is there a definitive list somewhere of what each combination means/or even what combinations are possible even if they can't be used?
My limited knowledge is that top row is piccolo ( 4ft ), middle row is clarinet ( 8 ft ), bottom row is bassoon ( 16 ft ) and that the number of dots from left to right is the number of reeds playing simultaneously.
And yet there can be 4 reeds?.....
Just need a little theory help in preparation for buying an instrument.
Thanks.
P.S. Can't be bothered with descriptive buttons as they would appear to be subjective and I would like an objective description applying to all instruments which is the dot system.

Thanks.looking at the first photo on the Wikipedia link it would seem that the term voice can be used for reed? So here we have two middle reeds/voices and no top reed/voice?

Nobody ever calls them high middle low 'voices' - they use terms like 4 voice meaning 4 sets of reeds - then usually referred in more detail configuration as LMMH - Low Middle Middle High (sets of treble reeds).
5 voice is usually LMMMH, but quite rare these days, and not cheap when you find them. Most 3 voice accordions come in LMM but not so common is LMH.

Most accordions in the UK 2nd hand market will have some degree of tremelo/wetness - usually because most either originate in Germany where the trad German tone has some tremelo, and/or because the biggest demand for accordions in the UK are Scottish & Irish - both having some or a lot of tremelo. You want some 'wet' you should be able to find it very easily. You want very wet, you can still find with relative ease. It would be harder to find dry, here.

For a blend of affordability and flexibility LMM would be OK for quite a few years for a beginner.

I'm not sure if I understood your comment correctly in another thread but 96 bass LMMM are also plentiful, and plenty wet to very wet examples there are too.
