Buying Antique Silver or Silverplate Tea Strainer Rotating Windmill Dutch Holland Netherlands True Vintage Item Repousse Edge

Charming antique tea strainer is 4.75 inches in length and features a repousse edge and is topped by a windmill with turning blades.

I have always believed this to be sterling silver — it is very lightweight as many sterling items are. But I cannot find a mark, and I don't want to damage it by trying to test it.

It would be a charming collectible for someone with a collection, or of course it is a serviceable tea strainer for someone who loves tea!
