G'day DONT 44 &Dave, more than possibly made by Camillus especially as the original paperwork stated this was so...however you read non Ellenville Schrade paperwork at your own peril collector wise....the Licence was flicked to a few....<its also why the knife has to be purchased to see the "inside" statements,as there is little hint it is not genuine Walden outside....reason why most Ebay sellers remove the paperwork and sell in empty tube or with no tube as it gives "the game away".....
I have both examples...the post 2004 I have wouldn't even cut butter,worst knife edge on any knife I own...feels squarish and does not sit comfortably in the hand like a genuine Schrade....<dont know why Camillus previously made knives for Schrade pre 2004 however its like the Camillus "Tobacco series stockmans....really average build quality which is why they sell for squat>...
Dave, you are right the number would be on the genuine knife.
DONT44 what is the number on the end tube paperwork in your photo?...<the guarantee portion has already been removed> dont know why anyone would fill out a guarantee on the post 2004 knife...<I can see enough of the paperwork to know its genuine pre 2004 paperwork and not the Taylor Brands "imitator"....sorry if all this info seems harsh however your original question was "any opinions as to its origins"?...Ebay sellers have been having a 'field day' at new collectors expense for the past 5 years....Hoo Roo
P.S. this was posted before I saw Hals' response...however I concur entirely with his statements.
