HUNGARIAN SURVEYING INSTRUMENTS
Summary This report contains
tivr hi inmcrta
information on six Hungarian-manufac-
the Sixth was ? an export version of one of the other instru-
ments'. Covered in this report are four 313 vels, one tachymeter?and.
one theodolite, all of which were allegedly original design products
of the Hungarian optical industry. Included as Annexes are three
sketches of two of the levels and the tachYmeter
described in this report9 plus a sketch of the reticle 'design used
in these instruments.

f. Weight?, Approximately 2 kg.
g. Type: Dumpy.
h. Primary Use: Leveling surveys.
2. Telescope
a. Magnification: 10 x.
b. Diameter of Objective Lens: 35 mme
c. Reticle Design: Centered horizontal and vertical crosshairs with
short horizontal marks dividing the vertical field into equal quarters (See
Annex B ketch of reticle design).
Leveling System
a. Type-, Location and Housing of Bubble Levels: Adjustable tubular
spirit bubble level in an enclosed housing 'along the left side of the telescope.
There was also a'bulls-eye level located in One Corner of the base plate
b. Number of Leveling Screws: Three.
Facilities for Viewing Bubble Levels
Prisms provided a coincidence view of the bubble within the telescope
ocular. Available light illumination was provided by a metal reflector, which
was mounted on the open bottom of the reflector housing.

o Miscellaneous Information
This, level cost 3,000 (Hungarian) forint.
. Facilities for Attaching Instrument to Base of Tripod
? Radiating from the bolt hole in the tripod base were three equally
spaced shallow grooves into which the leveling screws fitted and which helped
to align the tripod and instrument bolt holes. This level, as well as all other
instrument described in this report. 'was used with the Model 116F Tripod
