It's not just the fine blueing,or the best wood used!! Many gun makers mic the pieces and the closest to true tolerance go into the top of the line in that model!!! The rest get assembled into a lesser model of the same gun!
You will not get shotguns made by hand from step one to finish,unless you buy them from the era they were made like that(1905-?) and 1905-48,then 48-58,then modern hand made,hand fitted shotguns(damn near out of most of our reach)!!
The last shotgun I bought was an A5 light twelve(1957) it weighs less than my Rem 1100!!
You get what you pay for,the wingmaster is quality(but too much if all you want is an entry gun!!!)!
