Thanks Howard - good call (I'd completely forgotten that drawing!)
The section on page 189 of The Companion - and a certain amount of common sense - seems to concur; so bevel down it is.
Regarding the peg, no, I don't think so.
The brass section at the base of the column is staked on, but not with a continuous peg (being hollow inside for the other bits to pass through).
The parts list suggests it's a component of the worm / inner shaft assembly -

I can only presume BM19 is either the worm itself, or the inner shaft (it isn't illustrated), as BM 42 is the lower thrust washer, and BM20 is the elusive "peg".
I wonder could it perhaps be the "key" which locks the worm to the shaft?
