Rare 1937 Industrial Invoice – Karlstads Mekaniska Werkstad (Sweden) to Greece – Pre-WWII Maritime Commerce An exceptional piece of pre-WWII European industrial and maritime history. This is an official company invoice, dated July 28, 1937, issued by the historic Swedish heavy machinery manufacturer Aktiebolaget Karlstads Mekaniska Werkstad (KMW) in Karlstad, Sweden.

The total amount is set at 1,490 Swedish Kronor, with payment terms routed through the central offices in Athens. Features beautiful period typography, authentic signatures from the commercial department ("Kaufmännische Abteilung"), and a bold purple "KOPIA" stamp. Excellent vintage condition for a 1937 document. Crisp paper, very clear and readable typewritten text, with standard industrial archival punch holes on the left margin. No major tears or stains. Strong custom made packing, registered shipping.
