Howdy, fellow pipers.
A question for the Dunhill enthusiasts/experts, regarding grading of sand-blasts.
I have, in my collection, several Duhill's sand-blast pipes. A 5117 shell grain, a 6103 shell grain, an ODB 838 shell grain and a Dunhill HT Cumberland.
My question is, who or what determines when a shell grain is designated Ring Grain? From the 4 pipes I've listed, the 6103 (which I bought as an estate from Dave Neeb, thanks Dave!) has a most excellent sand blast and as such, could, in my opinion be designated Ring Grain, Dave also described the pipe as a Ring Grain that slipped through the system.
As for my HT Cumberland, which has a lesser grain effect, I saw another HT Cumberland for sale on SP, with what appeared to be a blast that was pretty much the same as mine and was stamped Shilling.
This ramble isn't a complaint. Just an observation, which has prompted my question.
Thanks in advance for any answers.
