I know this probably isn’t the best forum to ask this, but I don’t belong to any Winchester forums, and you guys know everything. 
Lately I’ve seen a couple of “Winchester Model 70 Super Grade’s” up for sale, that appear to be from recent years. (Not on this forum) Neither of them had SUPER GRADE stamped into the floor plate. Did Winchester make Super Grades that didn’t have that?
