I personally sculpted the masters designs in my Massachusetts studio. I have all the doorbells cast in Rhode Island. They are cast in durable zinc with an antique pewter finish. They are also hand polished and lacquered. I equip them complete with "Carlon" brand lighted buttons and stainless steel screws. •The Shamrock measures 2 1/4" tall by 2 1/4" wide •Lighted "Carlon" brand doorbell button supplied •Stainless steel screws supplied •Cast in durable zinc •Drilling may be required, but in most cases it's not needed. • Hand crafted in my Massachusetts studio. All my products are hand cast, polished, and package by me, therefore slight color variations should be expected.
