The rare 1920 S.28 code rifle

After the First World War, rifles remaining in German official hands were often stamped 1920 on the receiver as a property mark. That stamp is not a date of manufacture. The rifle underneath is almost always a wartime Gewehr 98 (or a closely related 98). The S.28 marking that appears on a small number of these rifles is scarce, poorly published, and therefore profitable to invent.

What it is not

It is not the Oberndorf military code S/42. It is not a 1928 K98k — the K98k did not exist. It is not automatically a Simson rifle merely because Simson is associated with 1920s work at Suhl. Each of those confusions appears in online sales copy.

How to look at one

Photograph the 1920 stamp, the S.28 (or claimed S.28), the original maker and wartime date, the barrel proofs, and the stock. Compare stamp depth and geometry with other 1920 property stamps on known rifles. A 1920 stamp that is too sharp on a freshly polished ring is a warning. A seller who cannot show the wartime maker under the later marks is selling a narrative.

Rarity is a claim. The wartime receiver date is a fact. Start with the fact.

If the piece is genuine, treat it as a Weimar-retained Gewehr 98 with an uncommon additional mark. Price it as a documented 1920 rifle, not as a missing link to the K98k.

Record the 1920 stamp and the original DWM, Erfurt, Amberg, or Spandau date as two layers.
