I have for sale a large vintage PAX zig zag marble machine

The model number is 580. It is made in West Germany, using colorfully painted solid wood and metal
To play, you insert the marble at the top hole and let it roll down five rail tracks, until it reaches the bottom
The marble enters the colored boxes and drops with a noise, to the next track going the opposite direction
Until it reaches the chained brass bell. It rings the bell as the marble rolls into the dugout pocket

On the bottom is printed:  PAX Nr. 580     W. GERMANY
It comes with one marble. Please note that the brass weight shown on the photos is not included

Approximate dimensions are:  21.75" wide, 22" tall, and 3.5" deep

I believe this is a very rare toy, from a lesser known company. I was not able to find any references anywhere online
This is a well constructed, high quality toy. That is in very good condition overall

Thanks for looking!
