Or, Mr Google; as an historian by profession, I am a rather proficient researcher. Primary sources, diaries, official records, written material, interviews, all called upon when needed- indeed, I am not too proud to read instruction manuals.
For now, I have the thing sitting (or standing at attention like a well mannered sturdily constructed sentry) here, beside me, on my desk. This has serious heft. Seriously, it could double up as a weapon, it is that solidly constructed, and well built - actually, it looks like an over-sized chess piece, plotting mayhem, murder and coffee making
..along with a (surprisingly brief) manual penned by OE Lido.
Their argument for a lack of numerals, or numbered stops, on the rim of the grinders is to 'encourage you to find your own settings'; again, as an historian, I find numbers easy to recall.
While I rather imagine that one will get used to counting off the indented grooves on the rings, (and perhaps sticking a small piece of marking, or identifying colour, on some spot), I suspect that a learning curve awaits me
