Technical Observations: The patina is pale green with some brown corrosion. The fibula is intact, although the tip of the pin is bent.
The body of the fibula was cast, probably by the lost-wax process, with the surface designs created in the wax model, while the pin was made separately by hammering. The catchplate was formed from the cast bow by hammering. The pin is attached to the body of the fibula by a thin rod, which seems to have been inserted in one end of the crossbar. This rod inside the crossbar may have been iron, as iron corrosion products are visible, but it is no longer magnetic. The surface shows rough finishing marks.
