Take time to absorb the scale of what you're achieving, not only the actual work - though that's awesome in itself - but rather the fact that you, by saving an ADO71, are one of a select band of restoration enthusiasts who can see the quality, the style and the dynamic prowess of a largely forgotten car through all of the cosmetic and structural challenges that time and neglect have placed in its way.
My own encounter with Princess ownership - AVG99T - was a very late example of the B series engined variety that had some of the detail touches intended to be seen only on the incoming O series cars. It was Pageant Blue, not the Tahiti that most mid blue 1800s wore, drank oil and petrol in very similar quantities (by which I didn't mean that it was incredibly good on fuel
..) and yet was much enjoyed for its comfort. I found a Reliant Kitten estate that I simply had to own, so swapped AVG for that with the part-time trader friend who had the kitten on his pitch. Now although I never regret obtaining another four wheeled Reliant, one of my main "what ifs" concerns that wedge and whether I shouldn't just have kept it and forked out cash for the Reliant. And that, right there is why my vicarious pleasure, in seeing your car being preserved, is so massive.
That o/e Philips is a far better device, just watch out for the tape eating antics that these can exhibit as a result of the takeup being driven by a toothed nylon gear rather than the far less brittle rubber idler tyre as used by pretty much every other maker apart from Philips and B&O-branded Philips tape transport mechs. They don't always let go but quality of the moulding was variable so if it still plays without issues then chances are it'll last. Philips' designs are famously bonkers but they rarely made a bad sounding piece of equipment.
