Inherited Wall Clock

by Dave
(Canada)

I received this clock when my father passed away, I cannot find any external markings.

It looks like a late 1800's Vienna style clock. It has a spring wound movement and gong (hour and half-hour)

I don't want to take it apart to see what the movement says on the back, and I can't seem to get a mirror in there to look.

Any help would be appreciated
