Another Kayser sewing machine (early zig zag)

 This heavy zig zag Kayser is similar to the Gritzner VZ B. I have found no way to date the machine yet, but it is suggested it's early fifties.

 Another nice cabinet. There was a bent old wooden ruler with this machine too.

 AN interestig feature are these double tensioners.

It's an early zig zag machine. Here you can see the zig zag and stitch length setting levers. The lever to set the needle left or right is at the back of the machine

Heavy and strong mechanical parts.
