Helius Designs Aureus mk2 Excellent Gimbal Tonearm w/Great Reviews Make an Offer

Offered is a great example of the Helius Aureus tonearm developed by designer Geoff Owen. The Aureus mk2 is a gimbal bearing arm finished in gloss black featuring azimuth adjustment via a collar located behind the headshell, gold plated bearings and two separately sized of counterweights. I briefly employed this arm to VERY nice effect on a Lenco design I once had. Completely blew away two different Rega arms. It gets high praise on a number of forum boards.

Check out the pictures, including the two counterweights and accessory mounting bolts headshell screws, and allen wrench. The arm is clean and sound but the non-painted bits do show patina and tarnish from age which in no way effects play and could easily be cleaned should you so desire. I have the manual and mounting page as downloaded and printed from Vinyl Engine.

Given the limited number of these arms that made and the very seldom seen offer of one for sale, I am unsure of how to price this arm. I thought of listing it at auction but, instead, I'll offer at this price and invite any and all offers. That said, understand if I ignore silly low-ballers.
