Estimate vary. Maybe as few as three or as many as 20 were made. Pictured in Sharps book. I tend to believe the 20 number because I know for certain that there were three. I owned one, given to me by Ellord Mott, RCBS has one in their press collection years ago and there was a third.
In any event I sold mine to Ron Peterson of Ron Peterson Guns of Albuquerque in 97. I understand that he still has it and that it is for sale. If you are interested you need to talk to Ron, no one else.
