This is a cool set, I’m guessing the drones are the regular 3 D’s with an A, and the single regulator ??? what notes do the 4 keys play on this set 
it looks like the drones are a little, well, i do not want to say warped, but they emerge at an angle. that may be fine but you would have to examine more closely.
regarding what notes, one would guess the tonic, the 4th, the fith and the sixth (DGAB) but would love to hear from someone who can more than guess.

It is supposed to be the old union pipe style, and all the old unionpipes I have ever seen have the drones come out of the stock at an angle… So, I think that is the look Brad was going for…
In the set in the photo, it looks like a normal baritone drone which plays (from top to bottow) A, G, F# and D. I don’t know if this is how the regulator on the early union pipes would have been keyed.
I believe that is the way they are meant to be.
Yes, it’s mentioned right on his details of construction page:
The mainstock regulator tubes are angled out from each
other, this spreads the regulators out slightly so the endcaps
don’t press against the adjoining regulators. The sockets for the
drones are also angled out for similiar purposes.
That is one nice set of Pipes.
I often toy with the idea of having a set of Union style pipes made for me, but then ‘She, who must be obeyed’ puts the bank book directly under my nose, and the smokey vision disolves. 
But I have to say, that a set of those in C is awful tempting. 
I would love to make a set in that style. Problem is I don’t know much about union style pipes, lack of research on my part… I dont know what notes the keys play on the single reg… Also, I’m not completely sure how the drone loops through the stock, although I have some ideas…
I guess I will consult a Mad 
Scientist
The front part of the stock is a plug which you remove from the stock to access the reeds. Part of the bass drone bore is contained within the plug itself.
I believe the keys on the regulator were F#, G, A, B. The fourth drone plays A or G, depending on preference - you change the pitch of the reed itself. Before you come out with the complaints about lack of versatility etc. remember that this is a faithful copy of early pipes - no keys on the chanter either. It’s supposed to be simple.
What key is the chanter in? I presume it’s not D.
D.
Have a look at this (8 key regulator):
Since its only a single reg, 8 keys wouldn’t be that bad (other than tuning issues). Its only when you want to start chording with multiple regs that you have to get more creative with spacing, etc.

I’ve heard this set and the boxwood original it was based on and both sound absolutely gorgeous. Brad’s set is a very faithful copy. I think the original might have been a Coyne, but I can’t remember (do you know, Kevin?)
The drones are indeed intentionally set in slightly angled holes in the stocks so as to better keep them from knocking againsts one another–I think this is a feature on all Angus pipes, although it does look particularly pronounced in this photo.
The chanters of both the original and the copy, though not quite as loud as the average concert pitch wide bore, were surprisingly lively sounding as I recall.
Brad tried selling this set on eBay over a year ago but nobody wound up buying it…Fools…
It’s J. Egan, who made a lot of these early pipes.
I remember a theory someone had about these one regulator pipes, that they were intended for polyphony - a constant countermelody to the chanter’s music - and when the second regulator was added it became a homophonic (simple chordal) accompaniment. The polyphony may have still been possible but it wasn’t as easy with one regulator. This was part of developing trends in art music at the time as well, apparently.
Yes! Historicaly minded Pipers: I was at Brad’s house in Feb. 2003 and got a chance to play the set under discussion. There’s no stop keys, you just huff up the bag a bit and then get it all sounding with a sharp squeeze of the bag. The drones (at the time the reeds in the drones were cane) overwhelmed the chanter, and the fix was all elder reeds in the drones. On the copy, Brad closed down the drones to bring about a better balance. The actual key is E flat. The oridiginal set, by J. Egan, belonged to Denny Hall of Gig Harbour Washington. Denny traded it to Brad for one of Brad’s B sets (Denny’s very happy with that set). Denny made copies of this Egan set, and Denny also made me a copy of the chanter, in Blackwood, after we both attended the year 2000 Tionol, at Seattle. I stayed at Denny’s house and tried his Egan chanter reed in my Pastoral chanter, and it played that chanter beautifuly. I put the 2 chanters side by side (with the C foot off the Pastoral chanter) and the finger holes lined right up!
My Pastoral chanter is by Fred Ord, circa 1993, copy of the Hugh Robertson set that’s in the Bagpipe Museum at Morpeth. That set is reckoned to be from the 1780s. Brad helped me to finish my Pastoral set by making a U bend for the Bass drone and making the regulator. Brad made the Egan copy for me , but I couldn’t afford it (perhaps another set in the future). I encouraged Brad to sell the Egan copy Union Pipe, and alot of the buyers were put off by the set being in Boxwood (as per the oridginal set) and not Blackwood! Anyhow I’m glad the set has a home and is finaly generating some interest… More Orders for Brad Angus?! Recomended by Sean Folsom!
