JOHN P. BRUCE.

The funnel is yellow or buff. The flag is a red swallowtail with white “A”.

Multiple exact-name and historical shipping searches did not establish useful independent evidence. Modern people-search results were rejected. The red flag and its A device remain source-only. The Rosanoski record is internally plausible for John P. Bruce of Dundee and cites Reed’s 1912 flag listing.
