Sunnen AN600 mandrel wanted

[WEAL]

Hello
Does anyone have a lead to a AN600 mandrel suitable for my Sunnen 1804 honing machine? I need one badly but cannot afford the new item. I have several friends in USA that would help with international shipping to Germany. I am dreaming of coming to the salt flats again with my own bike, had a lot of fun and disappointment with Max Lambky´s streamliner but I guess thats the way it is - for most of us...
Thanks for your help!

Best regards  Hartmut
