This item was purchased while traveling abroad. It is a hand-wound, working piece. The lid and body case are made of brass, and the manufacturer is unknown. The lid features a design of a steam locomotive. I was told it's over 150 years old. Excluding the reused parts, the diameter is 5 centimeters. As it is an old item, it is recommended for those who understand its nature. Please note that returns are not accepted. Price reduced.
