Wanted: TheobenBeeman Dual Magnum

Gentlemen, and Ladies:
Up until 3 days ago I didn't even know this gun was ever made. It was made in 2003 and 2004 and that might be it. It was made by Theoben, both to be sold under its own name and under the Beeman name, as the Dual Magnum. It was only made in .22 caliber and only for a year or two. It is a gas ram rifle but was unique in that you could use the barrel two cock it twice giving you achoice of two power levels. Th lower powerlevel was about 22-24 ft lbs but the upper power level was 33-36 ft lbs. I am interested in locating one, and I understand from my research that it will be pricey. Any information or leads would be appreciated. You can reply here or call my office: 319-232-2700. ( My phone gets answered alot more than my e-mail gets checked.) Thanks!

If I remember correctly there were only 81 of these rifles ever  made, so finding one will be almost impossible, but you never know.
 If you did happen to find one, get your check book out because it's going to be expensive.
I have never seen one on any of the auction sites or any classifids

I understand that they made very few,(81 is the number I have heard also) and I understand it will be expensive, but i guess I figure the best way to get a lead is to start the word of mouth chain here.  I am also checking some of the airgun classifieds.  I found an add for one for sale in Australia, but by the time I was able to contact the seller it was gone.  Any help I can get from anyone out there would be appreciated.  Thanks.
