The roll mark of the Importer and caliber are in the same font and on the same line. This is not a Parker Hale characteristic. The "BNP" proof mark is on the receiver and barrel and that's a good indication that the rifle was proofed in the UKicon. The confirming evidence is below the stock line. If you remove the barreled action there with be a proof pressure and dimension stamped on the barrel along with a set of crossed swords. There will be a letter to the right and number on the left., also a number in the sector where the swords cross. This will tell year of assemble and the inspector. See if you can get this info. It will answer all your questions on origin and caliber. It's a 1200TX without question. Ron (Canadaicon)
