NOTES  
                                   
Observed Serial Number Range: Lower and upper serial numbers of knives in my collection, viewed on eBay or from other sources. This is obviously an approximate S/N range.        
Number Made: Some totals are well known. However, due to the overlap of serial numbers for different knife types, other values are unknown.            
Blade Serration: TPI = Serrations measured in Teeth Per Inch                          
                                   
(a) Canted (5 Deg. offset) blades were made in the 001001 to 003747 S/N range. However, they may be found up to about S/N 004188 due to special orders.          
(b) Sheaths RT2, RT2S, RT3, RT3S, RT4 and RT4S are found with these knives. Refer to sheath table for serial ranges.                
(c) The "No. Made" quantity doesn’t include the 50 SIGMA knives made in this year. See the CT2S knife.                    
(d) Fifty Special Forces Presentation blades are marked in 2 lines on the Gerber logo side: "SIGMA" - GREEN BERETS / VIETNAM - 1968.               
(e) I have noted 4 knives in this serial range that had no trace of any Sigma etching. This casts doubt about the accuracy of the SIGMA serial range.            
(f) In simulated, red velvetene lined, black box with RT7 sheath and numbered, Pete Gerber signed COA.                    
(g) Blades etched in 2 lines on the Gerber logo side: Mark II™ / 20th Anniversary 1966 - 1986.                    
(h) Not all were sold in the black box with leather sheath. An unknown number of the 5000 were sold later (See note i).                  
(i) These are 20th. Anniversary knives w/o the blade etch. They were sold later with Cordura C3 sheaths in the blue & black box with "Mark II WASP  #GB5705" tag.          
(j) Total number of CS serial Cutlery Shoppe knives is approx. 1970 knives. The quanity of each of the 3 types is unknown.                 
(k) Knives CS0663 - CS0700 were not produced.                              
(l) Later blades etched on the logo side with Mark II™. Earlier knives are without the etch.                      
(m) Blades etched in 2 lines on the Gerber logo side: Mark II™ / 35th Anniversary 1966 - 2001 .                    
(n) These knives have a Cat's Tongue handle although the COA paper is similar to the 2002 Limited Edition Mark II and should have a black fused Armorhide handle.          
(o) 70th. Anniversary of the Gerber Legendary Blades Company (1939-2009). All blade marking is laser etched.                  
(p) Special order on any early knife with a S/N ending in "000". An unknown number exist.                      
(q) Handle changed from Cat's Tongue to Gray Armorhide.                            
(r) Special order with 10 degree cant. Stamped I.G.S. (Inglewood Gun Shop) above a 5 digit serial number.                   
(s) Knife name changed from "Combat" to "Survival".
