Thankyou but to tell the truth I am still trying to understand what I have. I went down and made a chamber cast and all the diameters are a few thousandths of an inch larger than those shown on the diagram in the above link at stevespages- very close. Also, it does appear to have three locks. The one shown in the above picture and two notches on the rib(not sure what the parts are called) that is part of the barrels and hinges down into the receiver.

The guy in Idaho that used to import Ferlach guns is:
Mountain Adventure Sports, 5045 Brennan Bend, Idaho Falls, ID 83401, 208-523-1545

Thank you for all the information.
