‘Poor Man’s Friend’ ointment pot, small size, priced 1 shilling and 1 and a half pence. Blue transfer on white. Prepared by Beach and Barnicott, successors to Dr Roberts of Bridport. It contained active ingredients effective for the treatment of eczma and minor skin infections. The brown patch is caused by iron staining that has penetrated the glaze.
I found a fragment of this bottle in Newfoundland, not surprising as we are just across the pond. My fragment is a bit smaller than yours. That contained some good stuff, berylium salts and mercury?
