The most obvious is that Case Brothers never used a shield that said CASE on it. Let alone a shield from 1960s/1970s like this one. The master blade tang has been obviously grinded down and a cold stamp applied - in fact the shoulder grind line on this one has been almost entirely removed.


65 pattern experts can probably tell more about when this one might have been made based on the frame, blade, nail pull, etc. It does seem to have bone (not the later Pakkawood) covers.
