The blocks slide back and forth instead of a slider plate.

I'd bet that's a bit heavy to play with a thumb-strap!

I've seen similar moving reedblock systems on two other instruments.  A Hohner's Morino club (picture below)  and a German concertina which I can't find photos of.  Paul Groff has the concertina now.

The Morino only has a single reed block to move.

Here are a couple of pics of that German concertina. It's MM, celeste tuned, with a similar stop (and sliding reedblock) on each side.

I wonder how airtight those systems are. Are the moving reedblocks sealed with leather, and does the leather wears down over time?

Seems to seal alright, but the resistance to movement can make for hard shifting. The concertina seems like it would lend itself to this though.
