Technical Observations: The patina features variegated greens interspersed with red and black corrosion. The pin is broken off at the spring and lost. The bow was cast and sealed closed. A black patch on the inside surface may be a plug. The core material and core pins seem to be preserved in the interior and are visible in the x-radiographs. The surface decoration appears to have been done on the wax model prior to casting, with some finishing after casting.
