Historic OGBL Cash Box / Strongbox – Luxembourg Exceptional historical cash box/strongbox associated with OGBL (Onofhängege Gewerkschaftsbond Lëtzebuerg), Luxembourg’s largest trade union organization. Dating from approximately 1970–1980, this heavy-duty metal box was likely used for the storage of membership contributions, documents, voting materials or administrative funds. Its impressive weight of 6.2 kg reflects its robust institutional construction. A particularly distinctive feature is the unusual top-mounted locking mechanism, accompanied by its original key, which is still present. The original OGBL identification plate remains attached inside the lid, directly linking the piece to an important organization in Luxembourg’s labour history. The box retains its authentic patina, wear and signs of use, adding to its historical character and originality.
