include—­stock-makers, barrel welders, borers, grinders, filers, and breechers; rib makers, breech forgers and stampers; lock forgers, machiners, and filers; furniture forgers, casters, and filers; rod forgers, grinders, polishers, and finishers; bayonet forgers, socket and ring stampers, grinders, polishers, machiners, hardeners, and filers; band forgers, stampers, machiners, filers, and pin makers; sight stampers, machiners, jointers, and filers; trigger boxes, oddwork makers, &c.  The “setters up” include machines, jiggers (lump filers and break-off fitters), stockers, percussioners, screwers, strippers, barrel borers and riflers, sighters and sight-adjusters, smoothers, finishers makers-off, polishers, engravers, browners, lock freers, &c., &c.  The Proof-house in Banbury Street, “established for public safety” as the inscription over the entrance says, was erected in 1813, and with the exception of one in London is the only building of the kind in England.  It is under the management of an independent corporation elected by and from members of the gun trade, more than half-a-million of barrels being proved within its walls yearly, the report for the year 1883 showing 383,735 provisional proofs, and 297,704 definitive proofs.  Of the barrels subjected to provisional proof, 29,794 were best birding single, 150,176 best birding double, and 160,441 African.  Of those proved definitively, 63,197 were best double birding barrels, 110,369 breech-loading birding, 37,171 breech-loading choke bore, and 54,297 saddle-pistol barrels.  As an instance of the changes going on in the trades of the country, and as a contrast to the above figures, Birmingham formerly supplying nearly every firearm sold in England or exported from it, trade returns show that in 1882 Belgium imported 252,850 guns and pistols, France 48,496, the United States 15,785, Holland 84,126, Italy 155,985, making (with 3,411 from other countries) 560,653 firearms, valued at L124,813, rather a serious loss to the gun trade of Birmingham.

Handcuffs and Leg Irons.—­It is likely enough true that prior to the abolition of slavery shackles and chains were made here for use in the horrible traffic; but it was then a legal trade, and possibly the articles were classed as “heavy steel toys,” like the handcuffs and leg irons made by several firms now.  A very heavy Australian order for these last named was executed here in 1853, and there is always a small demand for them.

Hinges.—­Cast-iron hinges, secret joint, were patented in 1775 by Messrs. Izon and Whitehurst, who afterwards removed to West Bromwich.  The patent wrought iron hinge dates from 1840, since which year many improvements have been made in the manufacture of iron, brass, wire, cast, wrought, pressed, and welded hinges, the makers numbering over three score.
