Product Name: Vtg Gilbert Mantle clock shop 1800’s.?
Up for grabs is this really ornate “Gilbert' mantle clock I'm assuming shop the age maybe late 1800's based off of the few minute research I did. It's pretty intricate in it's unique brass details labyrinth style door knockers with the lion head and marble look finish. It has a mellow ring that is chill not creepy all in all it's a great piece that will make any mantle look classy and purposeful. Condition is 7.8 out of 10 it could use a bath and detailing bc it sat on a mantle prob it's whole life. It winds up with a key but it hasn't been turnt up in a long time. I'm pretty positive it functions as it should I just have to locate the key. Any questions just ask thanks for looking!.
