Documentary images — company attribution uncertain

The attribution is assumed from a source showing funnels from 1875 to 1994 without company names.

Exact operator cannot be established from the chart.

Composite document joins Athenian Sea Carriers, Intestra, older Kyriakou liveries and foreign vessel companies. It internally gives 1969 and 1986 for the Intestra name change. K252 is expressly assumed, and K253's individual owner context is unresolved. Group identity cannot certify every mapped image as the same legal company.
