This is the second Codd bottle I have found, within a few weeks of the first, for which see here
Link for details. Like the first the bottle had its top broken to retrieve the desirable marble closure device from the neck.
Here, it has been washed and returned to its original finding place for the photograph, on a tumbledown wall in the woods close to the Afon Gwaun.
It is bears the legend GWYNFA MINERAL WATER WORKS FISHGUARD. This was a small factory run by the Bateman family and located only a short distance away, as the crow flies, across the valley at Plas-y-fron on the edge of the town. The place has been closed for some time but is still standing, see
