I have found Scholers in 3 sizes:
Large: Each side of the hexagon is 4 1/2 inches, 3 reads per note, so that each key plays in 3 octaves. Instrument tuned to C/G but tuned flat enough to be annoying when played with instruments tuned to modern concert pitch.
Medium: Each side of the hexagon is 4 inches, 2 reads per note, so that each key plays in 2 octaves. Instrument tuned to G/D but tuned flat enough to be annoying when played with instruments tuned to modern concert pitch.
Small: Each side of the hexagon is 3 1/2 inches, 1 read per note. Instrument tuned sharp of D/A so that it is almost midway between D/A and Eb/Bb. In Adam-T's photo, the small on on the left must be one of these.
I have some with the pearloid "Mother-of-Toilet-seat" finish, some red and some grey, and some with the wood finish with the fake wood grain painted on. I originally bought the first one in order to cannibalize to fix different 20-button branded "Frontalini". The Frontalini has the pallet style button mechanisms, except they are metal, like aluminium or steel, and its reeds are perfectly in tune. When I found myself with a large Scholer that was the wrong size to cannibalize, I thought the 3 octave tuning was so cool, that I would get another one the same size, and use the parts from this other large Scholer to fix the first large Scholer. But in the construction of the second large Scholer, glue was used too liberally, so that it is rather difficult to take it apart and keep its parts intact.
My advice about Scholers is to avoid them, no matter how cheap you find them. The wood they are made of seems to be better suited for making matchsticks, the tuning is always off, the reed are not mounted separately, but instead groups of 10 (5 in 5 out) are mounted together each on a common trapezoidal red block.
If you want a simple wooden-ended 20-button, so you can look like a more authentic 19th-century sailor, then get a Hohner D40. If you want that parallel octave thing going on, then Stagi makes a 20-button that does that.
I'll take some photos and post them when I have some more time.
