Very interesting Alan! We can always count on you to be thorough.
Of course I have a couple of questions:
With the key pad strip: are the large holes over the large reeds and the tiny holes over the small reeds?
Having played the Suzuki soprano a lot and working on reed organs. I know it takes more air-pressure to play the high end reeds.
I’m thinking it might be helpful to have wider holes over the smaller reeds?
Sometimes my physics understanding is faulty so maybe I’m wrong there.
Since it seems to be the same reed plates and reed cover I’m going to guess it has the same moisture blocking air problem that plagues the 37D?

Finally to get a bit personal Alan. Are you enjoying playing this melodica?
