This is a blue plastic covered board folder with 20 transparent plastic pockets glued to each cover. Five pockets contain the remaining colour photographs (152mm x 102mm) from the D.8890 series, four contain the odd prints without negatives.
The photographs show the marking up of every part and section of the tug that was carried out before work commenced to facilitate rebuilding at some future date.
There are 7 additional photographs that appear to have been taken while dismantling was in progress.
