Rbl. F. Flak: Artillery Sights

Rbl. F. Flak: Artillery SightsThe Rbl. Flak is used with heavy antiaircraft guns for indirect fire against ground targets and for reciprocal laying. A modified type is designed for use with the predictor.

When mounted in their respective sockets with the azimuth scales set to zero, the line of sight of the panoramic telescope on the predictor is 180° from that of the predictor telescope. The reason for the eyepiece of the gun sight being 90° from the axis of the gun is for convenience as the operator can stand at the right side of the gun and look into the sight at right angles to the axis of the gun. This sight is 9.3 inches in height.

Rbl. F. 40: Artillery Sights

Rundblickfernrohr 40 (Rbl. F. 40): Artillery Sights The Rundblickfernrohr 40 is believed to have been designed for use with the 7.5 cm L. G. 40 or the 10.5 cm L. G. 42. A carrying case and two night lighting devices employed with the instrument were also recovered.

This is a panoramic artillery sight, consisting of an upright section approximately five inches long, supporting an objective head which has a full 360° traverse, and an eye piece approximately four inches long set at an angle to the base. The eye piece traverses approximately 200°, permitting the operator to use the sight from different positions. A knob graduated in mils and numbered on each ten mils is located near the center of the upright section and traverses the objective head. The lower section of the objective head is graduated in hundred mils, the even hundreds being numbered. By pressing a small lever near the adjusting knob, free traverse of the head for quick spotting is possible.

An adjustment for elevation is controlled by a knob on top of the objective head which is graduated in hundredths and numbered on each tenth mil graduation.

An unusual feature in this sight is that the adjusting knobs are click mounted to enable adjustments to be made at night without light.

Two night lighting devices are provided with the sight. One mounts on the left side of the eye piece and illuminates the reticle with a red light which is regulated by an aperture in the attachment. The other is worn by the operator for reading graduations on the sight and has an aperture selection for either clear or red light. It is held in place on the forehead of the operator by an elastic strap.

Weight of the sight is approximately 2 1/2 pounds.

Rundblickfernrohr 32 (Rbl. F. 32): Panoramic Telescope 32

Rundblickfernrohr 32 (Rbl. F. 32): Panoramic Telescope 32

Rundblickfernrohr 32 (Rbl. F. 32): Panoramic Telescope 32This panoramic telescope is used on all standard field equipment. It is a 4-power, fixed-focus type with a field of view of 10 degrees. The line of sight may be raised or lowered by rotation of the angle of site knob. The angle of site scale is graduated from 100 mils to 500 mils (300 mils in normal). The angle of site micrometer is graduated in mils from 0 to 100 mils. The azimuth scales on the vertical barrel of the telescope are graduated in 100-mil intervals; the upper scale, 0 to 64, is fixed in relation to the rotating head. The lower has two semi-circular scales numbered 0 to 32 and can be rotated independently of the rotating head. A knurled portion permits adjustment. The azimuth micrometer includes two scales graduated in mils from 0 to 100 mils. The outer scale can be rotated independently of the azimuth worm. Evidently the fixed azimuth scale and micrometer are used for initial laying of the piece and the second scale and micrometer are then zeroed and used to measure base deflection. A throw-out lever is provided for rapid setting in azimuth. A locking lever locks the azimuth micrometer in any setting. The reticle pattern is shown above.

The existence of Panoramic Telescopes 36 and 37 has been confirmed. They are believed to be very similar to the Rbl. F. 32.

Rundblickfernrohr 16 (Rbl. F. 16) and Rundblickfernrohr 16/18 (Rbl. F. 16/18): Panoramic Telescopes 16 and 16/18

Rundblickfernrohr 16 (Rbl. F. 16) and Rundblickfernrohr 16/18 (Rbl. F. 16/18): Panoramic Telescopes 16 and 16/18The Panoramic Telescope Rbl. F. 16, which has been replaced by the Rbl. F. 32 and 36, is still used on the 7.5 cm l. I. G. 18. It is a 4-power, fixed-focus type with a cross level and longitudinal level for checking the alignment when the telescope and bracket are secure to the mount. Since the levels are not readily visible in this position, a mirror is provided on the telescope. The elevation scale and micrometer of the head resembles those of the standard telescope, Rbl. F. 32. The azimuth scale is graduated in 100-mil intervals and numbered from 0 to 64. The azimuth micrometer scale is graduated in units of one mil. The throwout and locking mechanism is the same as that of the usual type of panoramic telescope.

The Model 16/18, shown herewith, is very similar to the 16.
