I've never seen this before, where a 4" soil pipe must have

made.

This was fitted into a 1960/70s council house.

Sorry the photos are poor, too many cobwebs etc.

Even into the 1960s, the building industry was suffering from
shortages of materials as a direct result of post-war rebuilding.
That resulted in quite a few innovative techniques being tried,
some successful, some not. Building a lot of identical houses
would be the ideal place to try factory pre-assembly and welded
steel pipes would need less material than traditional cast iron.

It could also have been welded on site then taken for hot dipping

No point in welding on site and then taking it to the factory for hot
dipping. Might as well weld it in the factory too.

Perhaps I was wrong,

Yes you are.

but I assumed it was NT's attempt at humour?

It doesnt do humour.
