Thank you Glug, yes they are 15 registers. So here I took 5 pictures showing 3 in each picture... from left to right or up to down if the box was in my leap...I think I can see 21 reed plates on one row, I'm guessing half of the rows have 20 plates.
So that's 164 reed plates, or 328 reeds.
Which is the correct number for LMMH or LMMM with 41 keys.
It also seems to have 15 register switches which would be a lot for LMH, 9-11 is 'normal' for LMMH.
But there could easily be repeats at the ends.
If you can do photos of the note motif all the way from left to right it would be easier to tell.
Alternatively you can take the reed blocks out and see what the switches do to the register slides.
