A Swift model 687M variable power rifle telescopic sight with parallax compensation (the ring around the objective lens is used for making parallax adjustments). Telescopic sights are classified in terms of the optical magnification (i.e. "power") and the objective lens diameter. For example, "10×50" would denote a fixed magnification factor ...
The BSA Meteor is a series of break barrel spring powered rifle first made in Birmingham, UK, in 1959 by The Birmingham Small Arms Company and the first BSA air rifle engineered to fit a telescopic sight. [1] It is one of the worlds best selling air weapons with over 2 million sold worldwide.

A Royal Canadian Sea Cadet looks through a machine gun sight.. A sight or sighting device is any device used to assist in precise visual alignment (i.e. aiming) of weapons, surveying instruments, aircraft equipment, [1] [2] optical illumination equipment or larger optical instruments with the intended target.
The pilot/gunner had to look into the narrow field folded prismatic telescopic sight at the top of the device, a drawback corrected in the later Mark II. After tests with two experimental gyro gunsights which had begun in 1939, the first production gyro gunsight was the British Mark I Gyro Sight, developed at Farnborough in 1941.
