This system is called Abney level. It was designed by Sir William de
Wiveleslie Abney (born 24 July 1843 - died 3 Dec. 1920) and is
popular in England and the U.S.A.
Sir Abney was an English astronomer and chemist
best known for his pioneering of color photography and color vision.
Sir Abney invented this instrument under the employment of the School
of Military Engineering in Chatham, England in the 1870's. It is
described by W. & L. E. Gurley
(*) as an English modification
the Locke hand level, noting that it gives angles of elevation and is
also divided for slopes, as 1 to 2, 2 to 1, etc. Since the main tube of
this instrument is square, it can be applied to any plane surface. The
clinometer scale is graduated to degrees, and read by vernier to 10
The original Abney level did not have a compass. It was simply a type
of sextant for measuring vertical angles on land, not using the sun
– no filters. Until its invention clinometers were either
very bulky (sextants were used) or were not very accurate. Abney
invented his pocketable level purely to fill a much needed gap in the
market. Surveyors welcomed his invention, but it was primarily used by
the military for artillery and engineering (creation of roads, bridges
etc). However, the addition of a compass was a much later invention and
it is possible, though not definite, that F.
was the one to make the

DE LISLE'S REFLECTING
1890 - 1945 ANTIQUE, BRITISH MILITARY ITEM USED DURING THE BOER WAR,
THE FIRST WORLD WAR AND THE SECOND WORLD WAR
This simple device was invented by General A. de Lisle, (1825-99). The
half mirror in the diamond frame reflects the observer's eye when the
instrument is suspended from the thumb and held at arm's length. A
sighting on a distant object through the clear glass will be on the
same level as the observer’s eye and its mirror image. In
model the mirror can be tilted by using the weighted arm running over
the scale on the arc as a “handle”. This will give
measure of the inclination of the distant object. A heavy arc is
constructed upon the lower part of the instrument. This
is jointed upon a vertical axis so that it may be revolved to bring the
mass of the arc either forward or backward, to take inclines upwards or
downwards, or to rest at an intermediate position to make the
instrument flat and portable. The arc has a stiff centre axis with a
radial bar, the edge of which forms the index. A sliding weight is
placed on the radial bar, which is sufficiently heavy when at its
greatest extension to exactly counterbalance the weight of the arc in a
horizontal position and to make the mirror quite vertical. In this
position it forms a simple Burel level.
A set of graduations are made
upon the arc, which are numbered 1 to 50. The radial bar index set to
one of these numbers gives the amount of inclination that will result
from the coincidence of the reflection of the centre of the pupil of
the eye cutting the object to be observed. It is calibrated for
gradients from 1 in 50 to 1 in 5.

The description given in this document reads as follows:

is graduated in mils and does not require a conversion from degrees to
mils as does the M1 compass."
We suppose that the M1 was identical to the standard Brunton pocket

definition. On many websites, the standard lensatic marching compass

alidade that could be used both with the compass needle to take
bearings and with the clinometer to measure elevation angles. The
magnetic needle oscillations can be slowed by depressing a thin piston
gliding through the transit locking screw. The clinometer scale is

curvimeter is also unique: one can measure distances of up
to one meter by means of the integrated mechanism. One notched wheel
protruding from the casing's side indicates 100 mm. Each full rotation
of it causes a small wheel to advance by one unit. It bears numbers
from 0 to 9 (decimeters). These values can be read through the two
heart-shaped windows on the rear face. Further characteristics:

DESCRIPTION - A square protractor is an instrument utilized to measure
the geographical position of any point on a map with UTM grid reference
describe it for a user of the same map. It
is graduated with one or several scales in a vertical and an horizontal
Old models generally consisted of a square frame with several scales.
The distance between
the point and the grid lines is measured simultaneously with a
horizontal and a vertical branch.
In the 30's and 40's, there was in Germany a famous cardboard flyer
called Wehrsporttafel No. 12
especially printed for
the paramilitary 'defence sport associations' (Wehrsportgruppen
which explained the use of the square protractor (which could be
