Qualcuno o compagni tedeschi hanno questa piastra o induttore di cucina elettrica a casa? Marca – [Schott Ceran] Azienda tedesca. Hai idea di che anno è stato fatto? Non riesco a trovare da nessuna parte online – la mia attuale paese di residenza in Malesia.

Well it looks ancient, the voltage might indicate whether it was made before or after 1987. If it says 220V, it was before 1987.

Edit: Thinking of it, it’s made of metal and doesn’t have a grounding pin. That’s not only super scary but even more an indication of how old it is. I assume 1950/s1960s. And no, nobody in their right mind would use something like that nowadays – and you shouldn’t either.

Since it’s not a ceran hotplate, but metal, it probably is from the last century.

The color of the paint and the design looks to me like it’s from the 60s or early 70s.
