This Technical Manual TM 5-4320-220-25P covers the Barnes Model 10-MG Centrifugal Pump, identified under FSN 4320-820-0700, and is dated June 1965. For collectors of U.S. Army technical manuals, military pump and utility-equipment references, Cold War support-equipment literature, and dated government publications, this is a strong period document tied to a specialized piece of Army field and maintenance 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 Barnes Model 10-MG Centrifugal Pump
The Barnes Model 10-MG Centrifugal Pump belongs to the broader family of military utility, fluid-handling, and support equipment. As identified by its nomenclature, it is a centrifugal pump, 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 moving liquids for field support, maintenance, utility, and service applications where dependable pumping capability was required. In military service, pumps like this could support a wide range of activities tied to water movement, transfer operations, maintenance support, and general utility functions. 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.
For collectors, this manual has strong crossover appeal for anyone interested in military utility machinery, pumps, mechanical support systems, and U.S. Army field-support equipment. The inclusion of FSN 4320-820-0700 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 5-4320-220-25P would have been intended to support the maintenance and parts-identification functions for the Barnes Model 10-MG Centrifugal Pump.
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 pump and utility equipment during the Cold War period.
Historical Significance
The date June 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 utility and support equipment required to sustain field operations. Manuals like this reflect a period when Army documentation extended into every part of the logistical chain, including pumps, maintenance tools, fluid-handling systems, and field-support equipment.
For collectors and historians, this manual is especially relevant to subjects such as:
Because it covers a specialized centrifugal pump 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 5-4320-220-25P for the Barnes Model 10-MG Centrifugal Pump, identified under FSN 4320-820-0700 and dated June 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 organizational, field, and depot maintenance, repair-parts, and special-tools structure behind a military centrifugal pump used for utility and field-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 pump documentation and support-equipment parts systems. For museums, it helps explain the behind-the-scenes machinery that supported fluid transfer, utility work, and field maintenance operations.
