MANCHESTER SHIP CANAL CO. LTD.

Lloyds 1904 gives an enhanced small o in M360’s flag lettering.

Loughran gives wider white than blue bands and consequently larger letters. Rosanoski presumes his later Brown versions correct this.

The flag repeats the two funnel bands with the company initials added. Bakker follows the National Maritime Museum example. Its recorded dimensions are 1016 by 1879.6 mm, but the transcribed date range is the inconsistent 1955–1867.

M653 is retained from merseysideviews and British Steam Tugs.
