All About Pocket Knives

I read that the sciprt (no circle) Remington stamp that is underlined means that a knife was
a 'contract' knife built for Remington by another maker. Is that right, and if so, is the same true
for the underlined 'Remington' stamps that are inside the 'circle' ?

Thanks

The "straight line" Remington stamp was the mark of a contract knife. The "Circle" stamp was a Remington manufacture.
