The Birmingham Gun Barrel Proof House was established in 1813 by an act of Parliament at the request - and expense - of the then prosperous Birmingham Gun Trade. Its remit was to provide a testing and certification service for firearms in order to prove their quality of construction, particularly in terms of the resistance of barrels to explosion under firing conditions. Such testing prior to sale or transfer of firearms is made mandatory by the Gun Barrel Proof Acts 1868-1989, which make it an offence to sell, offer for sale, transfer, export or pawn an un-proofed firearm, with certain exceptions for military organisations. 1813 is a common year starting on Friday (link will take you to calendar). ...

The barrel of a gun or other firearm is the tube, usually metal, through which a controlled explosion is released in order to propel a projectile out of the end at great speed. ...
The Proof House still exists today, largely unchanged in both purpose and construction, although it offers a wider range of services including ammunition testing and firearm accident investigation.

The Proof process is that of testing a firearm for integrity using a severely overcharged cartridge, or Proof load which is fired through the gun in an armoured testing chamber. This exposes it to pressures far beyond what it would experience in normal service. It is awarded a stamped Proof Mark if it survives without either being destroyed or suffering damage from the proof load. Rimmed, centerfire . ...
Proof may be rendered invalid if the firearm is damaged or modified significantly; at this point it is described as "out of proof" and must be re-proofed before it can be sold or transferred.
Note that the correct term for a satisfactorily tested firearm is Proofed, and not Proven.
Penalties for noncompliance with proof laws are severe; a fine of £5000 (approx $9000 US) may be levied for selling an unproofed or out-of proof firearm, more if a number of firearms are involved in a transaction. Tampering with, or forging a proof mark is regarded as even more serious.
The Proof House is located in Banbury Street, Birmingham, England. It contains a museum of arms and ammunition, and can be visited subject to prior arrangement. See also Birmingham Gun Quarter.

An Englishman from Birmingham named Alexander Parkes developed a "synthetic ivory" named "pyroxlin", which he marketed under the trade name "Parkesine", and which won a bronze medal at the 1862 World's fair in London.
Parkesine was made from cellulose treated with nitric acid and a solvent.
PVC in its normal form is stiff, strong, heat and weather resistant, and is now used for making plumbing, gutters, house siding, enclosures for computers and other electronics gear.
