Harris, let's run through the visual, stem to bowl - the stem is really well cut, fine shouldering, good looking buttons. The adornment is pretty big on that barrel, but it's a pretty large diameter and I think it's not TOO big, which is to say it adds some visual definition against the bowl size (and the smooth rim which also attracts the eye). Shanks look pretty straight (not seeing taper in either direction really, but it's hard to tell on blasts).
The bowl on the black pipe is...not as good as on the red. The chin is over cut lending a Dublin-ish look to what is really a billiard shape. The red pipe is chubbier, looks like a better billiard shape to me. And really this is just to say that it's easier to slightly miss a billiard shape than to get it.
They're not factory pipes, they're not Danish because the shaping frankly isn't quite good enough and the blast is too good, as it were. Stem work is good and the shanks maybe just a hair heavy, so to me these are American School pipes, if Rad made them I wouldn't be surprised, but a guy like Wayne Teipen comes to mind too.
These are fusion-pipes, right? English stem material, Danish bowl treatment, English Blasting ideals, that tamarind or spalted birch detail on the stem is.. a bit busy for most Danish makers. But the whole pipe for the most part is excellently constructed, so I call American.
