West Germany Christmas ornaments

"West Germany" hand blown glass vintage Christmas ornaments. Plain: red / green / gold. 20 ornaments in total $40 the 20 are: eight / 2-inch Red balls, eight / 2-inch green balls and 4 / four-inch goldish balls. All,except the 4 gold and 3 of the 2 inch, have their original hook with wire holding it in the top for hanging. I'm pretty sure these are European Mercury glass. The person I got them from back in the mid '90s said they were from the '30s or '40s.
