I used to have one of these. It was found by an acquaintance in a drawer of a bedside table, amongst the hairnets and bobby pins, at a local estate sale.
The table and contents were all for one price. He asked for a price on just the knife and they just gave it to him. He sold it to me.
The knife had Rogers bone handles, was unused with a great etch.
I showed the knife to Bernard Levine in Eugene in 2001. He declared it counterfeit, as there wasn't a choil cut into the master blade. He also did not like the etch.
Everything about the knife looked "Robeson" to me, including the etch.
The trefoil GS shield was a bit proud of the handle. Pretty sure the shield was not pinned through the liner, but glued in place.
It had a great GIRL SCOUT etch with the trefoil GS logo between the words.
It too, had a steel pin in the master blade. The pin that went through the bail and the pen blade was nickel-silver.
No longer my knife, so I will not post a photo.
I have had several mint Robeson knives with steel pins. Cannot account for why or exactly when they did that, but for sure in the mid-1950's on some Strawberry Bone handled knives. The GS knife, however, predated that time period. I think they are 1940's knives.
I'm not a Scout collector. There are folks here that probably understand the possible origins of these knives better than I. There are a few examples known and of the knives I've seen, none had a choil on the master blade.
As to the bone on the OP knife, that is one of the circa WWII Robeson bones, IMHO.
I would explain the end-all, prove-all tell for a counterfeit Robeson knife, but not in this forum.
I will say, though, the OP knife passes that test.
