Definately not a Maxi joint from the pictures. There is a large hex visible on the ball joint body so it seems they may be screwed into the
wishbone/upright adapter which would make the Metro balljoint a strong possibility.
you right, think ive made that mistake before, i know the raw capri uprights use something different, maybe thats what I got confused with.

A plate welded across would stop individual pipe stress at the welds
Something similar to those found on 7's

As has been pointed out, that is a Metro balljoint at the bottom, not a Maxi.
I've just uploaded a typical Sylva/Escort/Capri front set up (on my car) for you to compare. Mine has a lower rose joint, attached by a through
bolt. The bottom of my Escort upright isn't a taper fitting, it's a very crude stepped hole, it your's is the same, then a taper
joint is probably inappropriate - it isn't going to locate properly? It may even bind??????
OK - I doubt that Sylva (Jeremy Philips) if he built the wishbone would use 1mm tube! Sylva were agricultural in the extreme, the bushes on my
wishbones are simply vast, secured by 13mm bolts(!) The wishbones themselves are boat anchors. Sylva weren't subtle.
1mm tube is simply not what should be there, destroy the wishbones and make new ones now if they're all like that. Do it now

As I said, maybe I don't remember correctly the dimensions of the tubes and possible they are bigger and thicker...I'll let you know.
I'm going to measure it tomorrow, now the car isn't at my house.
Looking at Google images, the balljoint seems to be the Metro one as suggested.
Thanks everyone.

3/4" 18swg tube would not be a problem if a half decent steel is used and welded well.

If you post a biggish picture on showing the fracture surfaces and picture of the undamaged wishbone there are plenty of people on the forum who
can give some insight as to how the failure initiated. On the face of it looks like a weld with a significant flaw acting as a stress raiser
leading to a fatigue crack which grew to the point of sudden brittle failure.
With welded joints like that the devil is in the detail of the design, blindly using bigger or thicker tube or welding on random fillet plates
isn't the way to go, any modification should be carefully thought out to avoid introducing a new point where failure could initiate.

I confirm the diameter of 19 mm and the thickness of 1 mm.

Well as it was the weld that failed I would suspect that the size wouldnt be the cause, however that does seem rather underspec. How well do you know
the history, could it be that its had a replacement made for it outside of the OEM spec?

To me that just looks like a bit of bad luck and a dodgy weld, which your bound to get a failure rate. Just look how many of these are out there.
As for saying jeremys wishbones were stronger, that is one of his. Ive not long had new ones on mine and the RAW ones dont have a nut welded on to
them, they have a threaded boss. and pretty sure there are 1.5mm wall.
But i doesnt matter how thick your wall is, if the weld is poor it will fail.
Good job your ok and it wasnt raining when it happened
