I shoot a pair of FEG 300's sxs 12ga and they are a well made, although very utilitarian(average wood, blueing) but they do have cocking indicators and single selective ejector with the option to use as a non-ejector. Sales of FEG long arms are pretty limited to imported used weapons, I believe that some new FEG's were sold in Canada.
I was able to find one picture of a FEG combo gun and appears to be a combo set of barrels on their 1000 series O/S shotgun frame. You might find more info looking up FEG O/U. I shoot combo guns from Bernardelli 5.6x50R Mag/12ga and BRNO 5.6x52R(22 Sav HP).
