Wersi AP6 Bass Synth

[julcanada]

Hey all

I have a beautiful condition wersi bass synth. It's not the kit version that was sold at the time. I am trying to figure out what these units are worth roughly, can't find much info on the interweb.

that's exactly this one: http://www.till-kopper.de/wersi_bass.html

Anyone could help?

Cheers
