Does anyone have any idea as to what brand these knobs might be and whether they are still available? They are on my MiL’s cabinets and she would like to add some more to additional cabinets.

I would love to be able to find them for her. I’ve done some searching and they are similar to a some items from the Richelieu ‘eclectic collection”, but I am unable to find this exact one.

Any help or guesses would be sincerely appreciated.
