For self-loading pistolas, the new mark was a "P" inscribed inside the same bomb.Proof marks are stamps applied to various parts of a weapon during and after manufacture to show that the weapon is safe for use with the ammunition for which it was designed.

The Spanish proof stamps changed in the very late 1920s and very early 1930s, so there were what I'll call "early" and "late" versions of interest to us here.At present, these include Austria, Belgium, Chile, Czechoslovakia, Finland, France, Germany, Hungary, Italy, Republic of Ireland, Spain and the United Kingdom.A number of other countries have their own forms of proof, either in-house or centrally run.Serial number/date of production records are hard to find for Midland guns, one source suggests they were lost in a fire.Based on what information I can find, and the style of the proof marks, I’d estimate a production date in the 1920s.They were quite a large company, at one time in addition to making shotguns they also marketed firearms (such as Winchesters) imported from the US.

Though not considered a “prestige” brand on the order of Purdey, Holland & Holland, or Westley Richards, Midland shotguns were considered to be sound, well made, reliable sporting guns at a reasonable price.

However, proof under earlier Rules of 1875, 1887, 1896, 1904, 1916, 1925, 19 remain valid provided that the barrel or action has not been materially weakened or altered so that it no longer conforms with that proof mark.

Foreign proof marks Prior to June 1980, there was reciprocal agreement for recognition of certain foreign proof marks, by international accord. has been working since 1914 for the standardisation of proof, which also involves standardisation of pressure measurements, of chamber and bore sizes and cartridge dimensions. It should be borne in mind that all countries have made changes in their proof marks from time to time and it is not practical to include within these pages all the proof marks that have been used over many years.

The Rules specify the pressure to be used in proof, standards of view and the marks to be impressed on guns which pass proof, together with such detail as bore and chamber dimensions, proof and service pressures.

The latest Rules of Proof, those of 1989, were approved by the Secretary of State, to come into force on 1st November 1989.

An early one - the Eibar "single and final proof for self-loading pistols and revolvers," a lion rampant (standing on one foot, more or less, and rearing dramatically).
