Didn't PJ and Aaron buy a Sandow on eBay? Considering there have only been like 11 Mr. Olympias, you'd think they would be rare collectors items unless a factory in China is making them and slow-releasing them.
I think the Singerman Sandow maybe came from someone connected to the Weiders, probably Ben. At the time, the seller also had a Cyr Strongman trophy which was used during the Arnold Classic Strongman show. If they both came from the same consignee, then it would have to be someone important enough to get their hands on both a Sandow and a Arnold Strongman trophy.
Unless the same foundry or artist was used for both the Sandow and Arnold trophy, and they sold them off.
