I'm still confused by the focusing thing. I'm presuming that new A7W reflectors with dedicated APF bulbs are fixed focus and all will be well through lens which have stippled glass and no focusing ability in R47s - i.e. there are no possible adjustments to be made.
But I'm weighing up whether the scuttle lamp system with reasonably good original reflectors can be BETTER than this? (accepting they will be 2' further back!) One just tries the bulb in all three - at night - and picks the best? Surely we must have evidence building up for particular bulbs to ascertain recommendations/experience..?
