1972-1977. In 1948 Poloroid Corporation captured the on and off market for instant photography. Almost 100 years after the first instant camera was patented and went into production in 1857, Dr Edwin H. Land's process finally answered the requirement that instant photography be easy to use and clean in 1948. The camera design folded to a very portable size. The SX-70 made automatic exposures and a battery hidden in the film pack powered the self ejection of the exposed print. The ultimate atraction was that the user could watch the image develope before his very eyes. Acquired from Bernie Boston.
In 1886, the French Army introduced a 52-centimetre-long ( in) quadrangular épée spike for the bayonet of the Lebel Model 1886 rifle , the Épée-Baïonnette Modèle 1886 , resulting in a rifle and bayonet with an overall length of six feet ( m). German ordnance authorities responded by introducing a long sword bayonet for the Model 1898 Mauser rifle, which had a 29-inch barrel. The new bayonet, designated the Seitengewehr 98 , had a 50 cm (-inch) blade.  With an overall length of 5 feet 9 inches ( m), the German Army's rifle/bayonet combination was second only to the French Lebel for overall bayonet 'reach'.
