If you don't know or are just uncertain about your clock's movement, please feel free to send a question before risking a purchase. I welcome questions along with escapement photos when appropriate.  If you don't have either

or

, it would be wise to send the serial number on the movement and a photo if you are attempting to identify it.  Likewise, Escapement Repairs are best left to professionally trained and experienced technicians as novices frequently tend to cause more (and expensive) damage to delicate parts. The phrase "if you break it, you bought it" applies here.
