Czech glass - Zig-Zag decor

I started collecting pictures of this decor abut 10 yeas ago and only have a few shots to show for it. It is an undetermined company but based on shapes it could be Ruckl or Welz. The base is a combination of neutral speckled colors in a tight pattern that is seen on many confetti pull-up examples (i suspect they are the same maker) The powder decor on the surface forms a tight pattern that is distinct striking.

I strongly believe it was made between 1920-30 in Czechoslovakia; Please email me if you have any other shots of these pieces.
