Yes to the question of plumbers fittings, but here (USA) vintage fittings are needed as the current parts in plumbing supplies are made of thin copper and swaged into shape, not cast brass as I mentioned. Too thin to be effective as a ferrell. And yes, you could see the lathe tools supply source and pay very dearly for the option of having someone else pre polish the part.
The 3/4 I mentioned is for the pipe size.
