Found in Italy/ Brown Medicine Bottle
found a smaller brown bottle. It has 50 and 100 markings along with lines down the side. It appears to have two faint lines down the sides where I’m assuming it was made. The marking I.Z.B. 4 5 1 on the bottom with a symbol at the top that might be AMV. It’s about 4 inches tall. Assuming it’s a medicine bottle but wanted to find out more.
