Siwa was one of the Dutch manufacturers. They made automatic frontloaders later, well into the seventies IIRC. Not sure if they made them all themselves, perhaps the later models were relabeled. This one however is an authentic Siwa, made in the NL. The Siwa Grandluxe has a rinse system, I don't see anything in the ad though how that would work. 598 guilders wasn't bad. But a heater was 50 guilders extra and an extra lid 35. This is an agitator machine. A pulsator machine was 100 guilders less. Under the picture of the agitator it says: With the safe forward and backward laundry mover. According to this ad (from 1960) the price was low because it was totally Dutch made, so no high import taxes.
