4mm. finescale BR Class 17 “Clayton” Bo-Bo fleet number D8568 in green livery with small yellow hazard warning panels was produced by Heljan as a Special Edition for Modelfair.com (cat. ref. 17001) and released in 2009. The model is in good running order and condition. It is running with a NEM coupling at one end and a screw-coupling at the second end. Much of the added detail is fitted (except the snow ploughs – in packet in box). The printed code numbers sheet is also present in the box ready for placing in codeboxes. The outer box is in as-new condition, as are the inner foam linings ( the model still has clear wrapper) and the instruction/history sheet. Also contained in the box is the original purchase order from Modelfair.com dated April 2009..
