Hi jwealleans, the D 183 brake composite, one of your recent models, is one which I particularly like. I believe that at least one of these coaches worked on one of the services to Whitby from York or Malton. There is a photo in the book 'North - Eastern Branch line Termini' by Ken Hoole, page 142, with, almost certainly, one these coaches, in one of the bay platforms. Dated 6th March, 1952.
I've followed your work for quite some time and just love what you've been accomplishing.
All the best,
Market65.
