1960 Meisner-Jensen Aster 3 motor pump
Meisner-Jensen was a small danish company, custom building fire fighting equipment on order for Falck.
Due to the rear support stands, it was impossible to get an unrestricted view of the plate from any angle, so I took several photos, making sure I'd be able to identify it when I got home. I'm uploading two photos here, together they show the whole plate.
