I found this at the bottom of a small round bricklined on Sunday. At first I thought it was a Dr Jaynes Hair Dye, but after cleaning It reads: ???? R'S / ???? ID / HAIR DYE. Thanks for looking.
I love shards (of course whole bottles are better) and keep most so I am able to analyse the pottery/china/glass ratio to help pinpoint the age of the pit. Although the pit I found this shard in contained only shards, I was thrilled to find pontil age at the bottom.
Thanks for the research, that T H PETERS is the bottle I want to find whole! Looks like I found the bottom to the much more common Bachelor's Hair Dye.
