In May 1926 the then well-known shipping agents T.A. Bulmer & Co. published a book titled MIDDLESBROUGH SHIPPING FACILITIES. I have scanned several pages from this book where vessels can be identified, but I start with a nice view of Middlesbrough Dock:
It can be clearly seen that the central ship has a name of 7 letters .... but what is it. Even under a magnifying glass I can't quite make it out - most annoying!
My first guess was LANRICK but Miramar lists only Gibson coasters with that name. LATVIAN looked a strong possibility until, quite surprisingly, Miramar did not disclose any vessel ever carrying that name. Then again, is that a Brocklebank funnel she has??
