This is an English Antique grandfather clock retailed by Tiffany & Co of New York. It has a five tube movement made by Elliott and Co of England. I date this clock from c1903.
The tubes are marked “Walter H Durfee”. For a period of time, Walter Durfee held the right to import tubes from England. He added his name and retailed them to USA clock makers.
The case had two glass doors, decorative inlay, and an attractive book matched veneer.
