.458 WM made by Harold E. MacFarland
Thanks for the kind words. I hope I can contribute positively to the forums.
As far as the white metal goes, it seems like the bolt, floor plate and sling swivels are meant to match. The trigger is a 2 stage that has quite a bit of travel, then it breaks like glass, similar to a sporterized .303 British that I own, except that the .303 is anything but smooth. The .458 trigger is the smoothest I have felt.
