My first antique grandfather clock

I would like to get more information about this hanging grandfather clock if possible. It is a Lombard clock with initials AC which i believe is the brass company. I think it was built in the 30's and was in a chicago hotel for many years. Supposedly it is 1 of 2 clocks of its kind. This is what i was told so i don't know how much of this info is correct. Thanks.
