Thanks Guys 
  
More progress this afternoon/evening dodging the rain showers, 
  
I stood the trailer up on its back end, screwed the floor boards in,cleaned it all up and gave it all a good coating of black waxoyl, 
not pretty but functional  
  
Also put the tailboard together, scewed the light board on and gave the wood a coat of varnish and the frame a coat of black... 
  
It did stop raining (briefly) so frame and mudguards also got a coating of black, then covered over with tarpaulins 
(raised off the paint of course), it won't be a concours finish, but hey, its a trailer...
