UPDATE- I won the eBay auction for this sight, $170 all included. I also am ordering a full set of screws from Evans Custom Screw & Machine, including the longer ejector screw for my application. I am opting for the 3 mm socket-head screw options with the allen key so adjustments can be made without stripping the slot-head original type screws. I will be installing the sight on a 1943 Maltby. The beauty of this sight is the fact you can switch to a different rifle, at will, without any gunsmithing needed. Mag Fed Canuk, if you don't mind me asking, where did you purchase your sight from and have you had the chance to test it out at the range?
