NB:Some years ago,I used to work in Gt.Guilford St,SE1,about 5 minutes stroll away from here.When it didn't rain,and the tide was out,I'd descend those steps on the rhs of the image and beachcomb.I found many different types of clay pipes.In those far off days,the floating dock wasn't there.It proved to be a wonderfully relaxing period,each day,which I would look forward to,as the job was very stressful.
