Well assuming the PORT ALFRED was the same Port and Starboard, looking at the picture on the top of Page 192, she has Round Ports all the way along the main deck passageway, whilst our ship has Oblong ones forward of the bridge like the INVERCARGILL on page 191 and she appears to have the two derricks at the bridge front.
Now could the Crane on the aft deck have been removed at the later date. The WSS picture is dated July 1960, quite early on in her life......
I see the Launceston still had hers in 1977 though.......
Anyway going off the Hull Design it has to be one of these.....ALFRED, INVERCARGILL or LAUNCESTON.
BUT have just spotted the picture of ALFRED on Page 149, THEY WERE DIFFERENT ON BOTH SIDES! and the Cabs look right.
No Crane......
So you could be right George even though it does look to be a longer name.........
Well anyway we have reduced the odds to Three.!
