There are 2 groups of "Friends of the xxxxx Park" as there are 2 parks there.. They will be glad to see you pick them up but not dig....Have you found any Media Milk Bottles or Media Medicne Bottles?
The first thing to do is look at the top part of the bottle or jar. If there are two seems there, you might just as well leave it there. These seams tell you it is an ABM Automatic Bottle Machine -made bottle. They have little value unless they are especially interesting. Look over what you have at this time. RED Matthews
