Product Name: Vtg Gilbert Mantle buying clock 1800’s.?
Up for grabs is this really ornate “Gilbert' mantle clock I'm assuming 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 buying the key. Any questions just ask thanks for looking!.
