Smalspårsboggier för 891 mm spårvidd? Pressad (Fordon: vagnar)

En av boggierna på bilderna ser gjuten ut. Någon som vet något om den..?

Om det är denna du menar så är den varmpressad av plåt.

Antagligen var N&H först, eller bland de första, i Sverige med att pressa boggisidor i och med att de levererade de pressade boggisidorna till de boggier modell 90 som Atlas levererade till SJ.
Deras vattenhydrauliska pressar drevs av plungerpumpar i förening med en ackumulator vars lock belastades med, om jag nu minns texten rätt, 400 ton tackjärn.
