ISO original doorbell backing plate and porch/atrium lights

ISO original doorbell backing plate. Did you get a newfangled doorbell but kept your old one? I'm looking for the aluminum backing plate for an Eichler doorbell. Roughly 1.5 by 3 inches. Please let me know if you have one and how much you would like for it. Am also looking for the original porch lights for the atrium and front door. Thanks!
