In the Schrade Collector's Forum, we noted these when they were first introduced in early 2005, I believe. There was a series of four or five folders and one fixed blade, all quite similar to the "Old Timer" knives of the defunct Schrade. I have the fixed blade, a Camillus CGP152 version of the Sharpfinger 152OT with the GranPa shield. I don't think they (folder patterns) were all shielded. The example I have was reviewed in the Schrade forum. This series was relatively short-lived and didn't make the ripple in the market hoped for by Camillus, though the quality from what I have seen was good.
One of my catalogs shows the...
CGP12 single blade 2-3/4"
CGP34 three blade 3-1/4"
CGP104 two blade 2-3/4"
CGP7 single blade lockback 5"
GP152 fixed blade 7"
Perhaps Mr. Williams (Camco) or Mr. Gibbs can give us more of the story on these.
