This practice became most organized, and earned the name of "proofing" with the advent of firearms, when armor plates were proof tested to assure their resistance to (proof against) early gunfire.
Though 100% of armor in those early days was tested, this rapidly changed to batch testing, which is what we have now with most firearms.
Probably the same year though, so its a good guide.
As implied above, with proof date codes, you can get an accurate and reasonably precise date on your Star pistol. The first three years of proofing (1927-29) were reportedly somewhat confused, so dates of manufacture may vary widely from the stamped date.
Three are proofmarks, and there is a fourth that is a Spanish military acceptance proof.
Although many other countries have military acceptance marks as well, I do not know their design; if anyone does know for sure, please send me a good quality photo or other reference information.
Though this system works fine for the Eibar-based Star, use care when trying to proof-date a gun by another Spanish maker.
I am not sure the same coding scheme is used for long arms, but try it and if it sounds right, it might be.
As seen below, there are four possible marks on any Star firearm.
A representative sample of each lot of weapons is tested with a proofing cartridge, which has vastly higher pressure than the normal specifications.
If the weapon survives a certain number of these, it passes, and all weapons in the lot get the proof mark to certify they meet the government's minimum expectations of function and safety.
Though the US government has inspection processes for military goods, there is no proof house of any sort for domestic US gun makers.
