The most important changes were the addition of a disconnector and a magazine safety, which hadīeen notably lacking on the vz.22. Additionally, it was trying to mass manufacture a pistol that was essentially still in the prototype stage.Ĭeska Zbrojovka (CZ) had to redesign the pistol for two reasons: 1) to adapt production to the existing machine tools at CZ, which would serve to speed production and reduce costs and, 2) to meet theĭemands of the Czech Armament Commission to make the gun reliable enough to serve as a military weapon.

According to Berger, Czechoslovak Zbrojovka had virtually no experience in manufacturing pistols and was not using modern manufacturing techniques that wouldĪllow for complete parts interchangeability. Perfect Joseph Nickl’s design since 1920.

The O3 example from my list seems to be one of these with that worded stamping on the reciever ring, made in the 1920's. Keep in mind, many recivers were made much earlier and not used until the 1930's to assemble complete rifles. PS: there was no Czech Eagle, it was a standing lion, small stamps being a stick figure. The E (L) date could also have been removed when re-built. Your rifle should have the standing lion reciever crest (after 1933) or perhaps be stamped CS ZAVODY NA VYROBU ZBRANI BRNO on the reciever ring, so it is a rebuild and was removed.

This is the date rifle was accepted by the Czech military but manufacture date should be close, at least the year. The only O3 on the list is E (lion) 35 (stippled over). My list of observed rifle serials shows all 3 series made from 1931 thru about 1936 (there is also a B4 thrown in that lot) Many have the E (lion) date stippled or peened indicating a post war rebuild. This was the Czech military serial system and was not used on export rifles. Is there a small stamp that reads like this E (tiny standing stick lion) and two numbers like 35? The 03 before the serial indicates rifle was made at Brno, if it was before the serial it would mean it was made at Bysterica.The o3 means it is the third time thru the alpahbet (do not know if they used all 26 letters).
