Mine is not a high grade. It is a field grade gun. At first I thought the Model 60 must have come out shortly before their sale to Ithaca but I know thats not the case using Krupp barrels. After the start of WWI Krupp barrels became scarce quickly. I doubt a small struggling maker like this one had a large supply of higher dollar barrels on hand. So I think we are looking at a 1913-1915 time frame. From what I understand they also made a number of low dollar guns for Sears also so perhaps the bulk of their production may have been under that area.
