This Technical Manual TM 5-6675-213-15 covers the Wild Heerbrugg Model T-2 Theodolite, identified under FSN 6675-232-8972, and is dated December 1961. This manual also covers the Model T-2 56, identified under FSN 6675-587-3767. For collectors of U.S. Army technical manuals, military survey equipment references, Cold War engineer material, and dated government publications, this is a strong period document tied to a specialized and highly important piece of Army field-support equipment.
Because this is a -15 technical manual, it belongs to the maintenance and service side of Army documentation rather than simple operator familiarization. Manuals in this category were intended to support inspection, upkeep, adjustment, repair, and overall serviceability of the equipment covered. That gives this publication solid technical value for collectors, researchers, and restorers who want original service-era documentation.
The Wild Heerbrugg Model T-2 Theodolite
The Wild Heerbrugg Model T-2 Theodolite belongs to the broader family of military survey, optical, and engineer support equipment. As identified by its nomenclature, it is a theodolite, placing it squarely in the support side of Army operations rather than in the category of conventional weapons or combat vehicles.
Equipment in this class was associated with precision angle measurement, surveying, layout work, and field engineering tasks where dependable optical instruments were essential. In military service, theodolites like the T-2 supported engineer units, construction operations, mapping and survey work, site development, and other technical field tasks where accuracy mattered.
For collectors, that makes this manual especially interesting because it documents the technical side of Cold War military survey equipment rather than more commonly seen combat hardware. It also has strong crossover appeal for anyone interested in military optics, engineering instruments, surveying equipment, and U.S. Army field-support systems. The inclusion of FSN 6675-232-8972 and FSN 6675-587-3767 adds cataloging value for collectors who prefer manuals with specific government stock-number references rather than only general nomenclature.
What This Manual Covers
As a maintenance-oriented technical manual, TM 5-6675-213-15 would have been intended to support the service and upkeep of the Wild Heerbrugg Model T-2 Theodolite and the Model T-2 56.
In practical terms, a manual like this is especially relevant for:
- nomenclature and identification
- maintenance and servicing guidance
- inspection and adjustment reference
- repair and upkeep context
- archival and restoration research
- technical reference for military survey-equipment collections
That makes it useful not only as a collectible, but also as a practical reference for anyone studying how the Army documented precision optical and survey instruments during the early Cold War period.
Historical Significance
The date December 1961 places this publication in the early Cold War period, when the U.S. military maintained extensive technical literature covering not only vehicles and weapons, but also the survey and engineer equipment required to build, map, lay out, and support military infrastructure. Manuals like this reflect a period when Army documentation extended into every part of the support chain, including optical instruments, maintenance tools, survey gear, and field engineering systems.
For collectors and historians, this manual is especially relevant to subjects such as:
- Cold War U.S. Army technical manuals
- military survey and optical equipment
- theodolites and field engineering instruments
- Army maintenance and service documentation
- dated military technical publications
Because it covers a specialized theodolite rather than a more common tactical vehicle or weapon system, it also adds variety to collections that already include standard ordnance or maintenance manuals.
About This Manual
This listing is for Technical Manual TM 5-6675-213-15 for the Wild Heerbrugg Model T-2 Theodolite, identified under FSN 6675-232-8972 and dated December 1961.
This manual also covers the Model T-2 56, identified under FSN 6675-587-3767.
It is especially well suited for:
- U.S. Army technical manual collections
- Cold War engineer and survey-equipment displays
- optical and military instrument collections
- museum exhibits on military engineering and field-support systems
- archive and research libraries focused on U.S. military technical publications
Because manuals were working documents, surviving examples are valued not only for their content, but also for their connection to real military maintenance and support practice.
Why This Manual Matters
Many military manuals focus on the primary vehicle, weapon, or combat platform. This one documents the support side of military readiness, specifically a precision survey instrument used in engineering, layout, and technical field work. That makes it especially useful for collectors who want to preserve the broader technical and logistical picture of Army operations rather than only front-line hardware.
For collectors, it is a solid stand-alone Cold War technical manual with a specialized subject focus. For researchers, it offers a useful reference point for Army survey-equipment documentation and maintenance history. For museums, it helps explain the behind-the-scenes systems that supported mapping, construction, site layout, and operational planning.
Ideal For
This manual is a strong fit for:
- U.S. Army technical manual collections
- Cold War engineer and support-equipment displays
- survey, optical, and instrument collections
- museum and archival reference libraries
- collectors of military paperwork and dated technical publications
