Ridgeway Mantel Grandfather Clock

Rec'd from father before he passed away in 2006. He told me his parents brought it with them when they came from Yugosloavia years ago. I have 1 key for winging. Therer's 3 pins that need to be wound. One I wing and it works the clock and pendulum. the chimes work and there's a lever to turn it off. Inside the back on the metal brass plate it's stamped 6  68. Also needs good cleaning. It also has the number 442854 stamped on it.
