1. No Prefix (1 – approx. 130,000) : The earliest commercial models. Some were later bought by the military, but true military contract guns typically start later.
2. "A" Prefix (A1 – A100,000) : Early war production.
3. "B" Prefix (B1 – B100,000) : The most common military production range.
4. "C" Prefix (C1 – C99,999) : Later war production, often with simplified finishes.
5. "S" Prefix (S1 – S~90,000) : Post-war commercial and "transitional" models. Collectors often avoid these for pure military value.

Using online "serial number lookup" tools often yields confusion. Here’s why: Here’s a concise review regarding “Hi-Standard Model HD

• No centralized government registry exists for these pistols.
• Aftermarket databases sometimes merge HD Military with H-D (WWII trainer, serials ~20,000-145,000).
• Best source: "High Standard: A Collector's Guide" by Charles Petty (2019) or the High Standard Collectors Association archives.

Quick verification method:
Take your serial number (e.g., 158,500) and subtract 150,000. Add to 1948.
Example: 158,500 - 150,000 = 8,500 units produced after late 1948. Roughly 1,500/month → mid-1949 production. This is a collector-derived heuristic, not factory official, but highly accurate. No Prefix (1 – approx

The Serial Number Range & Timeline

The Model HD Military was not a separate serial run from the standard Model HD. Instead, the "Military" designation refers to features (slotted barrel bushing, lanyard ring, parkerized finish, and non-adjustable military-style sights). Factory records show the following progression:

• 1948 – Early 1949: The Transition Era (S/N: 125,000 – 135,000)
  • The first true HD Militarys appear in this range. Look for a blue finish (not parkerized) and a "dog leg" hammer spur.
  • Key Feature: Slotted barrel bushing and lanyard ring.
• Late 1949 – 1950: The Standard Military (S/N: 135,001 – 160,000)
  • Shift to the standard Parkerized finish.
  • Introduction of the "straight spur" hammer.
  • Rear sight changed to the "Micro" adjustable style (though fixed sight models exist for military trials).
• 1951 – 1952: End of Production (S/N: 160,001 – 185,000)
  • Last commercial HD Militarys. After S/N ~185,000, the line was retooled for the M101 "Harper's Ferry" contract (marked U.S. PROPERTY).
  • Note: Pistols in the 170,000-185,000 range are often found with mixed parts (late frame, early slide).

• Features:
  • Adjustable rear sight (micro-click).
