Still waiting to see my new Howard low D.
Also been pondering why it costs more than four times the cost of my other five Generation whistles combined.
Any insight?
It’s more than four times the size of a Gen high D?
It will also be of more predictably reliable quality and it will also be a real bargain for a low D. I have a Howard low C which gives me something of that Overton sound I love for a lot less in price; not that I’d mind having another Overton of course. 
I was going to sell mine, but didn’t. It has some good points for sure.

Why buy those expensive Generations? Megs are about half the price.
I would think it’s about double the size of a high D Gary 
Not so Henke…
And, since we’re talking cylinders, there’s ghastly maths involved when calculating how much more metal and plastic there is in a Howard Low D Vs a Gen high D. Well, not so ghastly that the average teenager shouldn’t be able to figure it out, but I’ve never been average and it’s been so long since I was a teenager I can’t be 'arrised to work it out. It’s all about volumes and pies with square Rses.
But it’s more than double. Fank gawd Sandman wasn’t talking about a conical Shaw low D… 
Edited to add: and you can see how cr*p my maths is, since the original post actually reckons (accurately it seems) that the Howard costs 20 times as much as a Gen. Which is okay, considering my Overton cost about 40 Gens and is worth every Genny imo.
Because.
The bottom line answer is because people are willing to pay the high price. There is some relationship between price and performance, but it is definitely not a straight line. Musical instruments are discretionary items, not necessities of life. As such price often has little to do with materials, costs or any objective measures of quality. Perception is the key. There are no whistle commercials on TV or in magazines. So a lot of it is word of mouth or if some high profile performers start using a certain product.
We are lucky here on this board, because there are so many opinions, the vast majority offered with no ax to grind.
With luxury items sometimes setting a higher price will increase sales. A higher price often creates a perception of higher quality in markets such as jewelry, perfume, and any number of luxury goods. Whistles may follow the same trend because expensive whistles are luxury items. Sellers tend to set prices to maximize profits. There are few barriers to entry to whistle making so it is a relatively efficient market. New makers must decide on what market niche he/she is aiming at. Some makers look for a full time income, others do it as a hobby in their spare moments. This can be a factor in pricing decisions.

Yes. The Generation is mass produced in a factory, and the Howard hand-made by a beloved pipe maker in England.
Double the length
Double the width
Quadruple the size (volume) 
Musical instruments are discretionary items, not necessities of life.
That’s a joke, right?
Anyway, I finally put the thing in my mouth last night and my questions were answered. What a joy! I was worried about the size and spacing of the holes but it wasn’t a problem at all. And it sounds so … organic is the best word I can use to describe it. Plus, the bigger air column makes the whistle “alive” in your hands – you can really feel it resonate.
I’m a very happy camper today! Only 7 more hours of work until I can go home and play it again.
Actually, double width <=> quadruple cross section area.
If also double length, it’s eight times the volume of a high D.
Sigh…the Howard is double the metal length (less a couple of cm), and if you roll a Gen high D neatly around the inside bore, it goes round twice.
Definately four times Whistle-speak. Volume a few times too.
Productive time starts now…

So, the Howard has double the circumference of a Generation, which of course is equivalent to double the radius, which again is equivalent to four times the area. Definitely eight times the volume! 
OK, I’ll go to lunch now…
But! Let’s not forget the wall-thicknesses, else how can we determine how much more metal there is in the Howard? Plus, don’t forget to remove the amount of metal drilled out for the finger-holes in each whistle… 
I always did hate maths.
You are right..of course Where’s that “doh!” icon when I need it?
Volume or V O L U M E 
Here’s my thoughts on the subject:
We could do this dark ages stylin’ by getting a large container of liquid and seeing the difference in the amount of water displaced when you submerge each whistle.
Or we could pull out a periodic table and some scales and see which tube has more molecules in it (and by what factor). Of course this would be much harder if the material of either whistle were an alloy (brass) or something like nickel-plated copper. Would work great with pure nickel or pure copper tubes, you know. I like this idea but then we’d end up neglecting the fipple in the mix. oh well.
And the volume of hollow tubes isnt that hard to work out. Its just pi(r1squared - r2squared) times the heighth of the tube.
r1 is the radius of the whole thing and r2 is the radius of the bore. Speaking of bore, im boring myself. Yawn.
(pardon me if my math is wrong, I haven’t factored out so much as an x for about three months and its four in the morning.)
Sadly, the water barrel would be the most accurate method.
Those dudes really knew what htey were doing.
