Vintage ? Old Dutch Solid Copper Tea Kettle Wood Handle Brass Made in Korea

This is a tea kettle by Old Dutch International, Ltd. It is in very good, previously owned condition. There are some blemishes where the rivets are that holds the handle to the body and around the spout. The bottom has some mild scratches but no burner marks or discoloration. The cover of its tag states "imported handcrafted copper and brass", however, the first page of that tag says "solid copper". There is some residue that I was not able to remove that is visible in the 4th photo. The tag explains how to clean that residue. The tea kettle is approximately 7" tall with the lid, excluding the handle. Ref no 30506
