I'm familiar with Austin Healeys, a mate of mine owned one some years back, ridden in it lots and lots, and put 'essential supplies' (beer,) in the boot (trunk,) many times.
Until I saw that photograph I had never noticed that the boot hinges are standard Morris Minor 1000.
Never too old to learn huh?
And yeah, I too can only repeat Charlie and Uncle Bob's 'WOW!'
