This Technical Manual TM 5-3895-264-25P covers the Hopkins Model 200S Hot Oil Heater, identified under FSN 3895-066-6016, and is dated January 1965. For collectors of U.S. Army technical manuals, military construction-equipment references, Cold War engineer material, and dated government publications, this is a strong period document tied to a specialized piece of Army support equipment.
Because this is a -25P technical manual, it belongs to the organizational, field, and depot maintenance repair parts and special tools side of Army documentation. Manuals in this category were intended to support the identification of assemblies, components, repair parts, and special tools required to keep equipment serviceable across multiple maintenance levels. That gives this publication strong technical and workshop-oriented value for collectors, researchers, and restorers.
The Hopkins Model 200S Hot Oil Heater
The Hopkins Model 200S Hot Oil Heater belongs to the broader family of military engineer, road-construction, and field-support equipment. As identified by its nomenclature, it is a hot oil heater, 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 heating heavy materials and supporting maintenance or construction operations where controlled heat transfer was necessary. In military service, machinery like this fit naturally into the world of engineer units, road work, paving support, and general field-construction activity where dependable heating equipment was required to keep materials workable and operations moving.
For collectors, that makes this manual especially interesting because it documents the technical side of Cold War military support equipment rather than more commonly seen combat hardware. It also has strong crossover appeal for anyone interested in military construction machinery, paving-support equipment, and U.S. Army engineer systems. The inclusion of FSN 3895-066-6016 also adds cataloging value for collectors who prefer manuals with a specific government stock-number reference rather than only general nomenclature.
What This Manual Covers
As an organizational, field, and depot maintenance repair parts and special tools technical manual, TM 5-3895-264-25P would have been intended to support the maintenance and parts-identification functions for the Hopkins Model 200S Hot Oil Heater.
In practical terms, a manual like this is especially relevant for:
That makes it valuable not only as a collectible, but also as a practical reference for anyone studying how the Army supported heating and road-construction support equipment during the Cold War period.
Historical Significance
The date January 1965 places this publication in the Cold War period, when the U.S. military maintained extensive technical literature covering not only weapons and vehicles, but also the engineer and construction equipment required to build, maintain, and support military infrastructure. Manuals like this reflect a period when Army documentation extended into every part of the logistical chain, including road-construction equipment, heating systems, maintenance tools, and field-support machinery.
For collectors and historians, this manual is especially relevant to subjects such as:
Because it covers a specialized hot oil heater 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 5-3895-264-25P for the Hopkins Model 200S Hot Oil Heater, identified under FSN 3895-066-6016 and dated January 1965.
It is especially well suited for:
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 operator use or more visible front-line equipment. This one is useful because it documents the repair-parts and special-tools structure behind a military hot oil heater used for engineer and construction support work. That makes it especially relevant for collectors who want to preserve the broader technical and logistical picture of Army operations rather than only combat 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 construction-support equipment documentation and maintenance systems. For museums, it helps explain the behind-the-scenes machinery that supported road work, material heating, and field engineering operations.
