Based in Treboeth, Swansea.
Wrights 1899 Trade Directory lists T. Thomas, Penvillia Spring Aerated Water Co.
A trade diectory gives Penvillia Springs address as next door to Crystal Spring, no doubt they probably shared the same spring to fill their bottles.
At first glance all bottles from this company look the same, but there are subtle differences in the transfers
Four all white standard shape ginger beers.
These bottles are from the SMcD collection
Unfortunately I don't have an example of a bottle from this firm , if you have a bottle you would consider selling please use the link below to contact me.
Many thanks
Carl
