WTB - Pietta 1851 Griswold & Gunnison .36 7 1/2"

I am looking for a .36 caliber 1851 Griswold & Gunnison. It must have the correct round barrel like the one in the EMF link below. A good used one at a decent price would be as good as a new one to me. EMF said they could not tell me when they would get any in.
