I just started collecting bottles when my family started digging a foundation for a house extension. Even so, I tossed away all the broken bottles and fragments except those that were unique or interesting. One is a half of a bottle from Williamson W. Va. that has a circle with a capital M at where the 12, 3, 6, and 9 would appear on a clock and a capital F in the middle. The bottom also has a letter M. I am thinking it has something to do with the Masons. Any ideas?
