Going from the style of the case, the dial and without seeing the movement, I would put your clock at about 1900 - 1910. I do not have the exact model name in my reference material, but may come across it later. If I do, I;ll post it here.
I just bought a New Haven clock at a yard sale. I too can not find information about it. Can anyone tell me more about it? It has lions head on each side and 2 colums on each side of the clock. it still works..
