Dear boating fraternity

I am busy building the model Tug Diligent from the Model Boat Magazine from 2014.
On the front of the superstructure is a crest visible from the Port of Dover ,depicting the Lions from what I can make out.

Is anybody out there who could maybe send me a copy of such a crest which I could then use maybe redraw?

THANKING KINDLY TO ANY ONE WHO CAN BE OF ASSISTANCE
