Hi there, I have an old Hornby GWR 0-6-0 Pannier tank loco which I purchased on eBay a few years go and I want to add a decoder to it. The engine number is 2744. I'm not sure if it is an x.03 or x.04. There was apost made some years ago by Margate-Richmond - 13/10/2011 to be precise where he mentions that there is instructions he had made. Could some one direct me to that post, or help with instructions please. Thank you, Ian Bell (Australia)
