What it tells you

What this mark authorises you to say

On an Italian reproduction — the black-powder revolvers and cartridge-conversion arms that Gardone has produced in enormous numbers since the 1950s — this stamp is a legal restriction, not advice. The arm is proved for black powder, and loading it with smokeless powder is outside its proof.

What it does not tell you

What this mark does NOT say

It is not a statement that the gun is a reproduction rather than an original, nor that it is low quality. It also does not mean the gun is unsafe with black powder — it is the proof condition the gun was built and tested for.

Every claim above is attributed. The class of source is shown with each one, because a national proof house and an anonymous forum table are not the same evidence — and on proof marks the difference matters.

Reading marks to identify and date a gun

Proof marks name the test and the era. The serial number, where a maker published a browsable chart, can name the year. The lookup cites the threshold behind every result.
