Condition/Treatment
Wax seals attached to charters on parchment very often get damaged or lost. Seals fixed close to each other get worn when parchment bands are twisted or the charter is stored folded.
After flattening the charter, the bands were flattened individually. The damaged seals were cleaned and filled in with wax to avoid further damage. The charter will be stored laying flat from now on.
