Especially having trouble with the silver one. Original to 1929 home. Not sure the metal, don't know style terms to search for... trouble finding skinny knobs. Need total for 5 interior doors, no locks needed. A close match would be ok. The beaded knob is a little easier - I've found a deadbolt that's a pretty good match, but still looking for a regular knob - this one's for an exterior. I've found beaded knob but need to find one with a plain rosette (non-beaded).
