I should have known my post would require a follow-up reply that was more extensive than I usually have time for in my alloted daily computer PC time…
The short answer to the questions regarding my comment is this:
I have seen some of Bryan’s work, and some of Hammy’s work close up, and there is a difference in the workmanship, things that most people would not notice, but then I do make very expensive wind instruments all day, so I’m somewhat more sensitive to such things. What things? I’ll just list some examples, not necessarily comparing Hammy’s work to Bryan’s item for item, just general things that most people might not notice…
The bore - How smooth is it? Was it reamed with a good reamer and then sanded with multiple grades of sandpaper until it looks like glass, or does it still have some banding, ridges and roughness.
The rings, are they hand made or machine made, and how well are they made? Silver, steel, aluminum? Not always a given that they are silver, as Jessie pointed out.
Sockets and tennons, how well were they cut and finished, are there chips from tear - out? Are they completely concentric with the bore?
Tone holes and embouchure - how round, and how smooth, both inside and out? I’ve seen plenty of flutes where the holes have been drilled and then the maker has obviously spent no more than 5 minutes finishing the tone holes. This irks me since I often spend an hour working on a single instruments tone holes after the tuning has been done, in order to make the holes as aerodynamically free flowing, and cosmetically perfect as possible.
And so on, and so forth, I could continue ad nauseum, but I’m sure I’ve already added some nausea here so… 
Anyway, you get the idea. Some of this stuff affects performance, some, does not. I think Hammy makes killer flutes, they sound and play great, if you’re into Pratten Style instruments. OTH, I don’t guess he’s interested in making works of art, just really good flutes at a fair price. From what I know about Bryan, he’s a total perfectionist, striving for a somewhat different outcome with his work. Sometimes this means more manhours in labor, which can translate into higher cost.
