Are the BR steel wagons on the quay there in connection with the ship, and if so to carry what, I wonder.
The concrete barge is interesting.
The other two craft alongside are I believe part of Associated Lead's fleet. Other craft belonging to this company are also to be seen on my photo's of City Of Exeter and City of York. ( I will re-scan these two, hopefully to a higher quality).
There is elsewhere on NEM a mention of Associated Lead's craft.
