I have an octagon time and strike wall clock that has an American Clock Co. label on the backboard. This label states the company is a grand depot for the following makers: Clark and Gilbert, Brewster and Ingraham, Terry and Andrews, J C Brown and others. Inside the case are instructions for maintaining the clock (in English). The movement is unmarked. The case is very similar to a Seikosha octagon wall clock. Is the former a reproduction with false labels? Any info would be appreciated.
