They were a loved feature by his garden pond for many years. They look fabulous and are made from metal but not sure which as they aren't magnetic so maybe a Brass or Bronze alloy im guessing and they weigh 3kg each. The upright Crane stands at 83cm tall and the two other cranes stand at 64cm tall.They have a pipe connection at the base and spouts in the mouth for the water to flow through but I dont have any of the micro bore pipe you would need to test them and can only assume they work but they as im sure you will agree from the photos just look great as they are.
