I wouldn't think someone did it 'in-house' at Camillus. With the gaps in the spacers it does look to be a 'parts knife'. Someone likely purchased
the parts at Camillus 'fire sale' at the closing of the factory. Put it together and sold it at a Gun Show. It could have even been a ex-employee.
Still, it is a Camillus made knife. DM
I don't see any gaps?? Zooming in on the pictures, looks like shadows below the protruding springs of the partially open blades.
I have one of those, it's a favorite carry when I'm doing yard work. Comes in handy. If I had known how pricey these Camillus knives would get, I'd have gotten several!
