Anyway my questions a
What sort of door handles should I put on them?
Should I use an external latch?

My grandparents had a house done out in 1940s style, presumably during the
1940s. The doors had roller latches and pull handles. I can't find exact
matches on screwfix. The closest is:

But the originals were much more curvaceous in more than one plane and more
interesting looking.

Is closer (SAA Bow Handle 180mm).
