Need parts or new replacement for Arcadia old-style handleset
(palo alto, ca, USA)
We have an Eicher home with original Arcadia sliding door handles and locks. I understand parts for these handles or locks are no longer available. Can anyone recommend a new alternative replacement part or parts for the handle, including interior and exterior handles, lever for keyway and mortise style lock? Attached is a photo of one door handle and lock. What seems to break inside the lock is the spring. Also one of them is missing the exterior door handle.
