That back still looks like user damage, either reaming or heat erosion from aggressive lighting or smoking. I doubt it left the factory that way.I bought it estate. The front of the rim--the fat section!--was badly burned. Before I began work on it, I noticed the irregularity. I had to take a few millimeters off the rim to clear the burn. I measured it with calipers and the width of the sides of the inner bowl reflect the proportions we see from outside.

The back wall. ?I love that shape. Classic and stylish. Just ....seems to be missing something.....

As I look the pipe over, I'm agreeing. I can visualize how it used to be. What a shame!My thoughts is that the previous owner burnt the crap out of the rear of the chamber (arrow) and the pipe left the factory just fine. It's still a nice looking pipe.
