Kauri pine floorboard finish - non-yellowing, natural satin

Hi
I've read so much over the last few months I've lost focus. Need recommendations please on what sort of finish looks best on original 1927 Kauri Pine - non-yellowing, natural-looking satin finish.
Also any tips please on the polishing process? :;
I've been renovating my 1927 California Bungalow for 4 years now, so the last 'piece de resistance' is the floors. I've put off doing it as I fully intended to just use hard scrubbing with steel wool, carbide scraper, and orange oil cleaner, to leave the uneven floorboards for character. However now Im here, I just want it done, easy and looking clean. Thank you..... signed weary renovator! :wave:

Oil it, easy to apply and easy maintenance.

:iagree

Tung oil was traditionally used on floors. Tung oil finish these days may represent a close or a looser definition of tung oil. You don't want a formulation with polyurethane in it, or anything which will give a build on the surface. Conservancy is about maintaining reversibility or repairability, a floor with a film will eventually require sanding and floor boards have a finite and very small number of sands in them over their possible lifetime. It's been a while, and maybe I'm confused about what I used on a build-in I did which I thought I finished with Feast Watson Floor oil (I used to use FW Floor Seal for furniture, but it is discontinued and floor oil seems to have replaced it) but I thought this product did give a build despite tech support and the blurb indication it has no PU in it. It does have additives to help it cure faster though. It might be one to try. To be absolutely certain though I would use something like Gilly's tung oil, which has no additives. The down side is it takes up to four weeks to cure, although light traffic is OK after 24 hours. Pure Tung Oil – Gilly's Australia

You'll have to scrape the floor if there is a previous coating on it though.
