Jim,
This is going to be costly for an original. Take a look at Manions Auctions and see if they have one listed. Otherwise do a search for Militia collectibles on the Internet. In with some of the folks taht sell the original stuff, you should find dealers which sell good repro items.
I have listed Manions and you can just click on it for the site. Go to the "German" catalog and look from there. Good luck!
