There's no telling just what you might find on an *84* Spitfire ;-)
Seriously, what you found is normal. Your '80 Spit brakes plumbing
is not so unique. This arrangement can be found on '76 and later Spits.
'75 and earlier tandem brake systems used a "stepped bore" master cyl.
with different displacement and incompatible fittings all the way down
to the unions near the car frame. I went through this same frustrating
experience a couple of years ago, and then checked the manuals *after*
I had figured out how to work around it, like you did.

Yep, it would seem the aftermarket brake cylinders are like this. I
have
used two different brands (both made in Italy) with the 10mm bleed
nipples.
The flexible brake hoses being supplied these days also require metric
tools,
but thread into the calipers / rear fittings just fine. I hated to
"taint"
my car with metric hardware, but good brakes were more important.
