Ron van Doorneveld of the Netherlands sent the photo of an accordion reedblock (below). Ron accidentally sent two of the same photo, so when I get the other one, I'll post it for him.

I follow the discussion about the reedblocks on the forum. It's difficult to understand what all the members of the forum did mean. On the pictures beyond you can see the different between the manner of placing the reedblocks.

All the best
Ron van Doorneveld

Ron's correct name is van Doorneveld. Sorry for the TYPO!
