Barge TIRLEY, ex THEALBY (Flixborough Shipping Co.)-75, Harker’s yard no. 354, built 1973, 186gt.
She is seen lying at Sharpness and is for sale, or may have been sold, by Allied Mills Ltd.
Running mate CHACELEY ex NORA EASTING (Harker’s 316, 1964) had also been lying at Sharpness for some time, but she must have moved on. Both were for sale on the internet, £20,000 each.
