Hello Tatu,
Your chromatic button harmonica looks very beautiful, and I also like the small size and light weight.

What do you think of the harmonica reeds made by Harmonikas Louny Titlbach? There are 2 photos of the single reed plates here:

It’s difficult to tell from these photos, but these harmonica reed plates seem to be slightly thinner than the Italian made accordina reed plates by Binci.
Is there a forum member who knows the exact weight of a single Harmonikas harmonica reed plate ? (and in comparison to a single Binci accordina reed plate)

Did you also test your prototypes with a Borel style attached mouthpiece to it? The mouth/lips can get firm grip on the Borel and Dreux accordina mouthpieces.
Is there a big sound difference with yours not the extra mouthpiece? Did you experiment with this?
