Hello I had this FN B25 Express 9.3 X 74 R engraved by Gino Cargnel restored and fitted with new wood. The gun barrel at the bottom is engraved with the following code: "OOOBARS" does anyone know what this could mean? The barrel was tested in Liège 1976. The rifle is probably older.
He told me that it is a stamp from the test bench in Liège. The gun is tested until 3.600 BAR. The mystery has been solved -)
