IBIS (ca.1937) - the first generation

When IBIS was introduced, warfare had cast a shadow over the company’s history (The Pelikan’s Perch). Shortage and rationing had already begun. The economy model IBIS was the first to suffer the effects⁽¹⁾. In order to conserve gold for the war effort, IBIS for the domestic market⁽²⁾ was equipped with palladium “Pd” nibs (Fig.1) as of February 1937, the next year of its introduction.

I don't own any IBIS with Pd nibs, but it seems that several minor modifications were made in 1937 (or the next). In line with model 100, the recess in the middle lamella (Fig.2 arrow) disappeared from the feed (Pelikan-collectibles). The piston guide was equipped with a notch or ridge (Pelikan 100 (ca.1938))⁽³⁾ instead of a small pin.

Fig.3. are the posters of IBIS. Judging from the price, it seems a while after 1936.

Note;⁽¹⁾In the next year (May 16, 1938), models 100 and 100N were fitted with Pd nibs (Pelikan Schreibgeräte, The Pelikan’s Perch).
⁽²⁾IBIS with gold nibs was still exported to earn foreign currencies.
⁽³⁾The notch (ridge) fits in the groove on the piston rod, prevents the piston rod from rotating, and converts the rotation of the turning knob to the forward and backward movement of the piston rod. Please see Pelikan fountain pen (ca.1929).
