robinpeck,
That they are different models altogether is what SAUER,Eckernfoerde told me when I wrote them in early 70s asking them to replace the forearm on a prewar combination gun and make a new set of barrels.That the Fortuna was made in the Sauer factory is a rumor in the ROD and Gun Club.The manager was usually right,but I can't prove it.You can't go only by looks,take one of each apart and check/measure all the parts.
