This is an original Kendall Oil clock, new old stock still in the box. I opened it up to review the condition and take photos, otherwise this piece has been boxed up for the last 30 years in storage. It measures about 14 inches in diameter, it’s in excellent condition as seen with a plastic body and a glass bubble over the face. Untested but I don’t see any reason why it wouldn’t work as it should. It’s battery powered as seen. A beautiful piece to add to your collection, never have to upgrade. This is the only one I have. Note that there is dust/etc. On the box and packaging from years of storage.
