Black pipe.

Three things I'd fix :

The shank diameter is irregular, 360 degrees.

The gap between the stem and the shank at top.

The flat part of the stem (top view) has irregular sides, and comes out of the barrel off to one side.

Fix those and I think you have a nice pipe (if the inside's good).

Thank you! I will try to remember in the future pipes. But the gap is illusion. I looked at the pipe one moment ago and it was something whith photos, maybe dirt at the bottom.
