My mistake the Componar's and Componar-C's were triplet design but the Componar-S is 4 element, but in recent years the Componar's have been Schneiders budget enlarger lenses. Triplet lenses were re-introduced in the 80's as budget enlarger lenses, Componar-C's. at some stage in the late 90's the Componar-S replace them and the Comparon's.
