If I've understood the books correctly, all of the Scouts that Case actually made are pattern number 6445R. The ones that are stamped 640045R were made by Camillus, going back a pretty good way. I believe that Camillus made quite a few patterns under contract for Case, especially judging by how many of the Case branded "work" knife patterns suddenly disappeared when Camillus went away.
I agree...I believe that Camillus made the later examples of the electrican, hawkbill, and the rigger's or marlin spike knife after Case's in house versions of these knives were discontinued.
I go through this info in my book in more detail, but in short:
Case made the 12031 electrician with walnut handles until about 1982...then discontinued...then they contracted Camillus to make the 62031 LHR with jigged delrin handles starting 1n 1986, with the pattern changed to stainless steel circa 1990.
Case made the 61011 hawkbill with jigged wood handles until about 1981...then discontinued...then they contracted Camillus to make the 61011 with jigged delrin handles starting 1n 1986, with the pattern changed to stainless steel circa 1990.
The 640045R, from the Case XX stamp onward, was outsourced. I have seen examples made (IMO) by Ulster and also by Utica but I believe that starting in the mid 1960's and onward Camillus exclusively made the 640045R.
Case made the older style Rigger's knife the 6246 R SS in house until it was discontinued in 1978. Then in 1979 Case contracted Camillus to make the newer style 6246 L R SS with locking marlin spike. This pattern was discontinued in 1982 and then brought back briefly in the years between 2000 and 2004.
And yes the 61011SS, 62031LHRSS and the 640045RSS were all discontinued when Camillus went under.
Most collectors believe that Camillus also made some percentage of the 048 "slim trapper" patterns on contract for Case beginning in 1970 and through 1976 or 1977. The Camillus made versions have a slightly different appearance, different blade shape and blade grind.
There are other knives that Case has outsourced that would surprise a lot of people but I will save those for another day....
