Exploded parts diagram for vintage Remington Model 51 .380
Executive summary
The original factory exploded parts diagram for the Remington Model 51 (.380) is not embedded here, but multiple reputable sources host or sell the schematic and parts lists needed for repair or parts identification; commercial parts vendors (Numrich, Sarco), digitized gunsmith libraries (Firearms Guide), specialist retailers (Jack First, Hoosier), and long‑running collector forums all point to the same reality: the diagram exists and is available commercially or through enthusiast archives [1][2][3][4][5][6].
1. Where the exploded diagram lives in practice: commercial parts vendors
Specialist parts suppliers maintain the practical, working exploded views and factory part numbers that gunsmiths use when servicing a Model 51; Numrich (Gun Parts Corp) lists Remington Model 51 parts and schematics for ordering and cross‑reference [1], and Sarco’s parts catalog has a dedicated Remington Model 51 section where part listings and diagrams are typically provided to buyers [2], making these vendors the most straightforward routes to obtain the labelled exploded diagram and to order identifiable replacement parts.
2. Where to buy downloadable schematics and archival manuals
For those who want printable, searchable exploded views and original parts plates, the Firearms Guide family of services is repeatedly cited as the largest commercial archive of gunsmith schematics and original parts lists, offering thousands of printable schematics and armorer’s manuals that include factory parts numbers and diagrams suitable for professional work [3][7][8][9][10]; access usually requires purchase or subscription but yields high‑resolution exploded plates and parts lists for antique models like the Model 51.
3. Community sources and informal exploded diagrams
Collector sites and forums carry scans, photos, and community‑annotated diagrams that are often the fastest way to identify obscure small parts; a GunBoards thread points users to a specific exploded diagram hosted on a collector’s site (stevespages) and discusses part numbering and fitment nuances, reflecting how owners rely on community‑curated diagrams when factory sources are out of stock [6]. The Unblinking Eye and Remington‑focused forums also archive technical writeups and photos that clarify assembly and minor design variations across production runs [11][12].
4. Parts availability, fitment caveats, and pragmatic next steps
Replacement parts for the Model 51 are intermittently available from niche sellers such as Jack First and Hoosier Gun Works, and many collectors advise sourcing a “parts gun” because certain components (breech blocks, small pins) are rare or out of stock from mainstream suppliers [4][5][12]. Firearms parts distributors may list parts but be out of inventory, and a gunsmith library subscription or buying a printed schematic from Firearms Guide is often the reliable preparatory step before ordering parts [3][7].
5. Read this map before you take one apart—safety and version differences
Historic models like the Remington Model 51 had minor aesthetic and mechanical changes across years; community reporting warns that pins, springs, and frame drillings can differ between production runs, so a diagram must be matched to the gun’s variant and serial‑era before disassembly [6][12]. If the exploded diagram sought is for repair or parts matching, obtain a factory parts plate or vetted digital schematic from Numrich, Firearms Guide, or an experienced Model 51 owner to avoid mismatches [1][3][6].
6. Bottom line and immediate actions to obtain the diagram
The fastest paths to a labelled exploded parts diagram: 1) check Numrich/Gun Parts Corp and Sarco’s Remington Model 51 listings for downloadable schematics and orderable parts [1][2]; 2) purchase or subscribe to Firearms Guide for high‑resolution printable exploded views and original parts lists [3][7]; and 3) consult collector pages and forum threads—often they reference specific exploded diagrams (stevespages) and note real‑world fitment caveats [6][11]. If a particular small pin or spring cannot be located through vendors, the community consensus is to source a donor gun or commission a gunsmith to fabricate the part [12][4].
