A friend of mine dug this blue pot with a narrow neck in a 1900s - 1940s tip. Maybe some sort of later cream pot, or maybe a decorative small vase? I'm not too sure.
Thank you for that information, I need to read up on my poisons, I'm always amazed at how many variants there are! This one measures 4 3/4 (inches). They are a great bottle find, I've only ever had the one but a good find indeed
No writing on it except for BDH on the bottom, I think it stands for British drug House, I was told it was a lysol but I don't actually know very much about it. Dug it out of a 20-30s small farm tip... Pretty much everything else that came out wasn't very exciting, couple of hex poisons...
