I bought this rare looking antique door bell (I think so) from a friend in KL. I couldn't find the manufacturer's name or date anywhere on the item. Perhaps this piece was used in a school or office in the earlier days..(may be somewhere around 1940's or 50's. I tried to search for more information but there was none or even close to it. Maybe anyone out there who is expert in antique products can assist me with some information.
