This is a circa 1943 Robeson Perma-Lube 643645 four blade scout/utility, apparently purchased and mailed to one Ray Murchison stationed at the San Diego Naval Training Center by his friends and former fellow employees at Paramount Pictures following his enlistment during WWII.
That, of course, is assuming the knife has been in that box since 1943, which is the date on the mailing label. A bold assumption, I know.
The knife, however, is a great example of Robeson's inventiveness. The Perma-Lube knives had bronze bearings inlaid into the inside surfaces of the ends of the backsprings, upon which the ends of the blades bore and the knives opened and closed smooth as silk.
Earlier, Robeson had marketed similar knives in a line called, MasterCraft. They had the bearing inletted around the ends of the blade tangs and were horse-shoe in shape. Those, however, had a tendency to fall off, leaving the two or three little V shaped indentations to catch on the spring, causing the blade to stop in multiple positions between opened and closed.
After Emerson Case was hired to manage Robeson in 1940, it was decided to make the bearing part of the spring. They changed the line's name to Perma-Lube and most, if not all, these knives were fitted with a bronze shield.
The pattern numbers were the same for the patterns in both lines.
The MasterCraft and Perma-Lube 643645 scout/utilities are the most rare of all the various Robeson scout knife patterns.
I do not think the Perma-Lube line was produced for very long. They introduced it in 1940 and I doubt they continued it very far into WWII.
These are auction photos. The knife has been listed multiple times the past three weeks, with decreasing Buy-It-Now prices. I finally bought it yesterday and it's enroute.
I think this is a great knife and a very rare find. This is the only Perma-Lube scout I've ever seen and I've only seen one MasterCraft scout in a Bruce Voyles auction several years ago. I bid on it, but lost.
