Quick Identification Guide

Check for a prefix or suffix

Does the serial start with MT? → First Series Match Target

Does it end with -S, -C, or S (no hyphen)? → Go to Step 2

Plain number only? → First Series Sport/Target

Identify the suffix type

-S (hyphen-S) → Sport, Target, or Match Target (Second or Third Series)

-C (hyphen-C) → Challenger (2nd) or Huntsman/Targetsman (3rd)

S (no hyphen, 6 digits) → Third Series Integrated Block (1969–1977)

Use the number range to determine the exact series

-S: ≤ 146,137 = Second Series · 146,138–147,138 = Third Series transition · ≥ 160,000 = Third Series

-C: ≤ 77,143 = Second Series Challenger · ≥ 90,001 = Third Series Huntsman/Targetsman

94500	First Series (numeric only)
MT7000	First Series Match Target
35750-S	Second/Third Series -S
40600-C	Second/Third Series -C
030700S	Third Series Integrated
