Need information about this antique clock (Junghans?)

Hi every body. Recently I bought this beautiful clock case. I does not have the movement machine. Only contains the pendulum, regulator clock strike gong and the dial says Junghans, but I am not sure if this dial is original for the case. Could any body tell me if this is a Junghans clock and how old is it? Can I find the correct movement to install it?

Best
