Thank you so much for the information. Yes it is much like the one on the left, although mine appears larger and the lettering is taller and thinner.[:D]
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.
