As from July 25, 1949, 14 ct gold with "IBIS" imprint was available again for the export market (Fig.6) (Pelikan Schreibgeräte, Pelikan-collectibles). As from 1950, gold nib became available for the domestic market, too (Pelikan-collectibles), but CN nib was concurrently available (Pelikan catalog No.70/8 (1951)). In the same catalog, IBIS with gold nib had rolled gold doublé ("Walzgold doublé") clip and cap ring, while IBIS with CN nib had golden?("Goldin") ones⁽¹⁾. In 1951, gold nib with "Pelikan" imprint was introduced (Pelikan-collectibles). As from April 22, 1952, CN nib became unavailable for 100N. So, virtually only model 130 IBIS was available with a choice of CN nibs (Pelikan catalog No.80 (1953)). It appears that old feed (three lamellae) was consistently used until the model was dicontinued⁽³⁾. As for piston seals, white disc-shaped plastic seal was introduced in 1950. The black elastomer seal from the pre-war era was also used. These seals were replaced by the wide transparent nylon seal in 1953 (Pelikan Schreibgeräte).

This version may be the "postwar IBIS" in its true sense. The shape of the section is different from that of Pelikan 130 IBIS (ca.1949) (Fig.5). The section appears to have been changed around 1950.

Note;⁽¹⁾In the same catalog, 400 series and 100N (gold nib) had rolled gold doublé ("Walzgold doublé") clip and cap ring, while 100N (CN nib) had gold-plated ("hart vergoldet") ones. We can see that pens were differentiated by the two (three?) types of metal finishing.
⁽²⁾My pen has replaced black nylon seal.
⁽³⁾As for model 100N, old feed with three lamellae was replaced by new feed with four lamellae in 1950.
