Wow. That's an interesting one. Never seen an Ideale with the springs incorporated like that before. Their "casual", sprung mattress saddle, no doubt.

I would go ahead and clean it up and try it. Since it's not a stretched "suspension" type saddle as most of their offerings are, I wouldn't hesitate to clean it with saddle soap and oil it. The big question will be how badly the springs underneath have rusted.

Very interesting saddle.

Edit: Oh, are those "bungee cord"-like cords under there? I assumed they were cloth covered metal springs. But you're probably right, Chombi. In which case, rot will be the issue. But they COULD possibly be replaced, if you're in to dismantling that contraption.
