... simply by buying old machinery doesn't somehow magically endow the knife made with it with quality & credibility. In fact, a lot of the equipment at Queen was very agéd and likely decrepit, certainly their final knives reflected a lot of flaws in assembly, finish and aesthetics.
You have no right to charge for nostalgia.
Will, I agree with your statement about the machines. No doubt the old Queen machines are worn - especially if they date back to the pre-war or turn of the 19th-20th century knives. Did Mr. Cooper and company restore them before putting them back to work? I don't know. To be honest, I rather doubt it. Machine parts are expensive, some necessary parts may be out of production from before Mr. Cooper's daddy was born, rendering them "make it yourself".
At any rate, the people machinist running whichever machine every shift they are on for decades know "their" machine. They know what needs to be done to compensate for the perhaps a century or more of wear.
Without the training of a oldtimer that knows the equipment, a new guy isn't going to know all the idiocracies of that machine and tooling that may be as old or older than their Great-Great Grandfather.
I have to disagree with your statement "You have no right to charge for nostalgia.", however.

Nostalgia sells. However, there is no rule or law that says you have to buy it.
Examples? The Dodge/Plymouth PT Cruiser and whatever they called that open roadster. Also, the Chevy mini pickup and panel truck with styling based on the 1949 to first series 1955 Chevy/GMC pickup.
If not for nostalgia, why do cars from the 1970's and earlier
parts car sell for more today, than they did new?
The "beach cruiser" bicycles harken back to the 1920's to 1960's, when balloon tyre bikes were all the rage. Same for "BMX" bicycles of the 1970's to 1990's. (I think the BMX craze is over, but I may be mistaken)
Art Deco, "Rustic", "farm", Victorian, etc. home decor, tabletop and portable radios, wall and desk/bedside clocks, plumbing fixtures, etc. (I think most of my generation when "growing up" had a 2 to 3 foot diameter "starbust" clock (8 to 10 inch clock face) hanging on the living room wall. If not for nostalgia's sake, why are they selling today?

Also old photos from the 1950's to 19th century showing different areas of the hometown ... the downtown district, railway station, a school or library, etc.
I think vintage cutlery also sells because of nostalgia. Do people who spend big bucks for say a pre war to 19th century Case, Schrade, or Russell Barlow, for example, buy it to drop in their pocket and use, or for display to remind them of a simpler time they missed out on? I suspect the latter.
They make and sell wall hanger only replica guns, that cannot be shot. The muzzleloaders don't have a flash hole, cartridge guns don't have a firing pin. Many cannot be cocked ~ the hammer doesn't move.
Historical interest? Sure! But also nostalgia. Geo. W. wasn't the only guy to have a pistol like that.
Heraldry/Family Heraldry plaques, along with cossed swords or other medieval weapons hanging in a place of honor in the livingroom (or if you prefer "great room") ... Pride and nostalgia.
