antique clocks/ gramdfather door bell clock

Looks like small Grandfather Clock top with long tube metal which actually tells time, but also door a bell.  It has been in the home since my mother was a young child.  Over 65 some years. I don't have much history on the clock Grandmother don't remember she is 97 years old nor my Mother exact time. I recall through the years that it was quite pleasant door bell/chime.
