Firearm Identification & Dating

This section is designed as a practical collector’s reference. Each guide focuses on markings, serial number ranges, maker or arsenal identifiers, production clues, and model changes that help place a historical firearm in context.

These are text-first guides rather than specimen profiles. The goal is to provide a straightforward reference point for identifying and dating common military and historic arms, while keeping the actual guide pages clean and research-focused.

How to use these guides: start with the model you are researching, then compare serial ranges, proofing, receiver markings, manufacturing details, and variant features before drawing conclusions. On rebuilt, refurbished, or import-marked arms, individual parts may span different periods.
