I picked up a couple Westy rotating seat bases yesterday. Got them real
cheap because the dingbat who salvaged them only got the upper and the round
plate that sits inside. Making up a serviceable lower mounting surface
should be a snap, but I've never actually seen one! Is it not just
essentially a flat plate with a circular stamped-in groove and a slot at the
front for the rotation lock handle?
