I have a clear glass bottle, dug out of the river by my house. The seam doesn't run all the way to the lip, I has "ELLIMAN'S ROYAL EMBROCATION FOR HORSES MANUFACTORY SLOUGH" written on it in raised letters. Any information would be greatly appreciated.
Ellimans bottles are nice but fairly common, they also made the stuff for human use and packaged it in smaller rectangle shaped bottles.
Here is a photo of my different ones, yours is probably like the one on the left ?
