This pipe has no shape number stamped on it. And I am at a loss for what that number would be.
I have smoked it 3-4x now, with English Luxury. It is very efficient at removing moisture, and I get a dry flavorful smoke from it, there is nothing to impede the draft channel, it all gets wicked away.
As for cleaning, I just do my normal procedure. After I have smoked it a few more times, I will use the big fluffy cleaners w/alcohol and just insert them in the channel and let sit overnight. That should pull out most of the gunk. That's what I did when I refurbed it, though it took several days and more cleaners.
I don't use soapy water as it tends to promote oxidation.
