Unghans Wurttemberg W111 291 grandfather clock

I think its 1920s and is in great shape and works like new, as u can see i took it apart because i was going to move and wanted to keep it mint!! Is has a star almost in the center of the clock and within the star it has a "J" and abobe that it says Unghans!! Ont the back of the actual clock it say "Wurttemburg W111 291" The pictures should explain the rest!! Just very afraid when i sell cause were moving to a smaller place, im going to practically give it away or charge way to much and either never sell or rip someone off!! Please help me :-)
