Not much progress recently.  The entrance steps were found to have been knocked and rivetted together out of various odd pieces of sheet steel.  The basic framework is angle iron and saveable.   A new piece of mahogany board was purchased for the bottom step which was rotten.  Rebuild work started by shaping  the rounded forward corner piece and a new forward end piece has been cut.  This needs a strengthening flange folding in it but is otherwise ready to use.
