You are absolutely right David,thank you once again .regards.

My eyes are only a couple of years younger, but the "56" tug is the same as in the other photo (and to one seen elsewhere that shows the wheelhouse name-board clearly as MELITA V.

Thank you david, you must have superior eyes than my 68 years old ones and I am going to stand by your comment and alter the pic title.

I think that the one on the left, marked '56' is MELITA V.
