Case XX Trapper ~ Historical Tang Stamp Collection ~ Vintage 1997

• The Brand Logo: The main blade features the "Long-Tail C" in the word CASE, where the tail of the 'C' extends under the entire word.
• The 3-Dot Dating System: Case utilized a descending dot system during this era. Starting with 7 dots in mid-1993, one dot was removed for each subsequent year. The presence of exactly 3 dotsdefinitively dates the knife's manufacture to 1997. 
• "TESTED XX" Text: If your specific knife reads "TESTED XX" alongside the 3 dots, it belongs to Case's historical Tang Stamp Collection (or Antique Tang Stamp Series). These special-edition tribute sets were produced to honor original vintage stamps (like the 1920–1940 Tested XX era) while using modern dating dots to verify the actual 1997 production year.
