Hi All, recently picked up a horn shaped Stanwell. Seems to smoke great, but I've been having trouble passing a pipe cleaner. When I remove the stem, I see this little notch
I thought it might be drilled the same way as in the below diagram, but isn't the point of that design to facilitate passing a cleaner?
Appreciate any help.
