Proof marks also help in determining the nationality of manufactures when no other marking are evident. In England, the Birmingham proof houses were established by Royal charter to protect the public from the sale of unsafe weapons .A number of other countries have also established their own proof houses include Belgium , Finland , Germany , Italy and united kingdom.
- 3. Conts.. There are also a number of countries have separate military proof marks for service weapons. These once again are not accepted by the European commercial proof houses. Weapons bearing military proof marks have thus to be commercially proofed before they can be legally sold in those countries. There are basically three types of proof : 1.Provisional proof is only for shotgun barrels in early stages of manufacture . This type of proof marks is designed to prevent the manufacturer from continuing work on barrel blank which may have hidden defects. 2.Definitive proof applies to all weapons and shows that the weapon has been tested with an overcharge of propellant and missile 3.Reproof is an additional test which may be applied after a weapon has been repaired or altered in some way.
