Vintage Antique Late 19th Century-Early 20th Century SLATE LION MANTEL CLOCK!

The clock is in GOOD Condition, but I do NOT have the key and I CANNIT confirm that it is in working order. It can’t from a size able clock collection, so I am assuming it is. The clock features Lion Head handles on either side and Lion Feet. There is the remnants of a label on the bottom, but it is illegible.
