The barrel:

Condition:

The barrel box was unspoilt. The Maltese stopwork was available, the mainspring old and used. The barrel arbor was damaged. So the polishing scratched, the flange below for the stopwork unequal filed to fit an incorrect finger of the stopwork. The Maltese cross and the finger show a different height.

Process:

The arbor is reworked as far as it was possible and the surfaces got a new polishing. The Maltese stopwork could be procured from a friend in Glashütte. At last the barrel is completed by a new mainspring.
