Howdy Black River Smith,I measured two pinch blade Winchester front sight's that are original to the rifle's. They are both 28 in. oct. barrels ,one a 45-60wcf the other is a 45-75 wcf.They measure 0.250 from top of barrel flat to top of blade. They each have the Winchester ladder sight's equiped from Winchester. Hope this may help you,,,,,,Dusty
