Description
Soviet 10×45 “Donkey Ear” Trench Observation Binoculars – Original Tripod Mounted Observation Set
This Soviet 10×45 “Donkey Ear” trench observation binocular set is an original tripod-mounted field observation instrument marked ASZT 10×45 with serial number 511311. The binocular body retains the distinctive long offset eyepiece form that gave these Soviet observation optics their well-known “Donkey Ear” nickname. Paired with its tripod, and leather covers, the set presents as a complete Cold War field observation piece with strong military character.
Soviet 10×45 “Donkey Ear” Trench Observation Binoculars
These Soviet trench observation binoculars were built for fixed-position surveillance from cover rather than ordinary hand use. The raised eyepiece pattern allowed the observer to work from a lower and more protected position while still keeping the optics over cover or parapet height. That tall profile is the defining feature of the type and gives the instrument its unmistakable silhouette.
Construction / Configuration / Pattern
This example is marked ASZT 10×45 and serial numbered 511311. The binocular body follows the classic Soviet trench observation pattern with elevated eyepiece tubes, central mounting section, and tripod fitting. The leather covers remain present, which is an important detail on a set of this type. The tripod is in excellent condition and retains its correct military field form. The wooden construction elements also remain present, adding to the originality and period look of the set.
The 10×45 designation indicates 10-power magnification with 45mm objective lenses, a practical combination for field observation where clarity and steady mounted use mattered more than portability. Mounted optics of this type were meant for deliberate scanning, target observation, and sustained watching from a fixed position.
Historical Context / Pattern Development
Observation binoculars of this form belonged to the family of military optics designed for trench, field, and prepared-position use. Rather than serving as compact officer’s glasses, they were intended for longer periods of mounted observation. Soviet military optics placed a strong emphasis on rugged service construction, simple field utility, and compatibility with fixed supports such as tripods and emplacements.
The tall eyepiece arrangement reflects the real purpose of the instrument. It allowed the observer to remain lower behind cover while still using the glass effectively. That made this pattern especially suitable for forward observation, defensive positions, and controlled field surveillance. In that role, instruments like this formed part of the broader Soviet system of practical battlefield observation equipment.
Condition
The tripod is in excellent condition. The binocular retains its leather covers and presents well overall. The wooden construction tripod and the optical body together give the set a complete and coherent appearance. Taken as a whole, this is a strong original example of a Soviet mounted field observation binocular set.
