I’m trying to find an entrance handle similar to below in polished brass with matching knocker. I can get this set from America but it’s satin brass and they don’t have matching knockers. Anyone know of suppliers that might be able to help? I’ve had no luck, can only find more rounded style.

Sorry I have no insights but I am facing the same question (with the exact same doors haha) so following!

i second black, one of our clients mixed black handles with silver taps and it worked, it will definitely work with brass features as well. the black wont fade if cleaned with the appropriate products, just choose a matte finish with low grains

The clear lacquer coating has worn off. Brasso will clean it. But you will need to regularly do it as it will continue to tarnish. You could take the handles of and send them to a metal polisher who can strip them back, repolish and then relacquer
