Odd drilling in 1980s Butz Choquin Origine

I can't quite get a photo of this, so I'll just try to describe it. I'm refurbishing a 1980s B-C Origine No 2 with goose bone extension and it has the most unusual drilling I've ever seen in a commercial pipe. I've reamed it all the way to the bottom of the bowl using my very nice Iwan Ries cutters and It appears that unlike most bent pipes, the draft hole is drilled exactly parallel with the shank, leaving it quite low in the sole of the bowl. In fact, it end the level of the bottom of the bowl, so a hole is drilled at the edge of the bottom of the bowl which intersects with the shank's draft hole below. Of course, this creates a fairly tight bend in the draft and isn't ideal. It seems like a prescription for a gurgling pipe.
Can anyone confirm that this was typical of at least some of these Origine pipes?

I see an error in my original post that I need to correct:
The draft hole from the shank ends BELOW the level of the bottom of the bowl, so a hole is drilled at the edge of the bottom of the bowl which intersects with the shank's draft hole below.6
Here's a drawing of it:

It was pretty tarred up and still needs further cleaning, so I don't yet know how well it will smoke. I usually take a filthy estate as a positive sign of a well loved and well used pipe. This one could be an outlier due to the design issues. We'll see.
What I found very interesting was the degree to which the tars penetrated the goose bone extension. There were tar bumps all over the exterior, giving it a pebbled texture. A short soak in alcohol and a rubdown removed those exterior deposits and left behind a lovely shiny, dark, marble-like finish. Like some meerschaums, it's actually improved the appearance. Incidentally, the seller completely (probably innocently) misrepresented the pipe as an antique albatross and mother of pearl stemmed pipe. Thankfully, I strongly suspected a much newer pipe based on the mouthpiece, which looked to be acrylic, instead of mother of pearl, so my bid was appropriately low. This pipe is from the 1980s.

I've also read somewhere genuine albatross bone goes for $150-$200 per inch!

Good to hear! I have an unsmoked 14” threaded extension with silver fitments. Frank Burla told me it was worth at least $1500.
