Port and Stbd nomenclature was certainly still used in British Military Aircraft at least up to the (Metal) Harrier/Hawk T1 era (ie in parts catalogues and component names).
I officially changed over to L+R when I started working on Plastic Harriers (GR5 upwards) but it never bothered me which words were used - I was happy to use either system.
Same as I was happy to use any of the impressive list of different units for measurements and capacities,sometimes of course different units were used when comparing an export aircraft to a (same type of ) RAF Aircraft.
