Condition Report
Main scale intact, but becoming loose in places and will need re-gluing at some point in the future. Plugged hole in frame ¾" below lower shade, possibly a manufacturer's error. The reverse has a repair to the top pin foot with plugged wood below suggesting it replaces an earlier wooden foot. Brass work possibly disassembled and re-lacquered and reapplied at a later date. Some minor scuff marks caused by the index arm over parts of the upper frame surface. Left index arm top missing.
