The third release of "Originals of their Time" was a re-edition of the model 110, and is called "1931 White Gold"⁽¹⁾.
 
The original model 110 was introduced in 1931 (Pelikan Schreibgeräte). The model 110 was one of the precious metal models or “luxury models”. It was characterized by white gold filled cap and sleeve (and clip)⁽²⁾. The ground metal was nickel silver. The inside of the cap top metal was ebonite. The cap tube metal was lined with ebonite tube to reinforce it. The model 110 had three patterns (diamond, barley, and wave) on the cap and sleeve (Pelikan-collectibles). 
 
Returning to the modern 1931 White Gold, the pen, as described in the 1931 Gold, is found to be faithful in appearance to the original model 110, except for differences in the nib unit, filling mechanism and barrel construction. Of course, the cap and sleeve are white gold filled. Probably the pen is rhodium (or palladium) plated as white gold tens to discolor if left intact (Pen Cluster). The sleeve is decorated with alternating wavy patterns and plain stripes, probably only one type of pattern for this limited edition.
 
This limited edition has a metal cap and sleeve, so there is almost no celluloid problem, which has been pointed out in the previous series (although there is a possibility of denting when bumped), and it can be said that this is the highest quality fountain pen (as an industrial product). 1931 pieces were produced in honor of the year when the original Model 110 was launched. The original model 110 was so rare that its re-edition, 1931 White Gold, sold out very quickly (Pelikan Schreibgeräte).
 
The only problem, to some extent to be expected, would be that the white gold body would tarnish yellowish over time. I don't know if this is due to the rhodium (or palladium) plating on the surface peeling off or the discoloration of white gold, but I have seen several 1931 White Gold with yellowish discolored body more than 20 years after its release. This may not be enough to be called a drawback, but, like all other pens, this 1931 White Gold is now fetching a high price, so prospective buyers should be aware of the discoloration of the body.

Note;⁽¹⁾According to the catalog, the name of this pen is "Originals of their Time 1931", and although it does not have "White Gold", it is customarily referred to as "1931 White Gold" for the sake of convenience to distinguish it from other 1931 series.
⁽²⁾White gold is an alloy of gold and at least one white metal (usually nickel, silver, or palladium).
