I now have eight of them. My newest one is a new model, S\/N 07308871. It’s the best looking one I have (close to NIB). \n\nMy question? It has a glue on sticker about 4” down the fore stock. \n\nIt says: Tested And Targeted by - Phil B. Marlin 493405 with the Cowboy on Horse symbol under.\n\nShould I leave this on the gun? \n\nDoes this add or subtract from value?
