Many thanks CK for your thoughts above (30/10) concerning your Manor. I have since decided to stick with it and conduct some further running-in sessions in the hope that it will bed-in and give slow, smooth starts & stops. It is a lovely loco and I'm very impressed with the appearance - at least I was - until the chimney came off! Now before anyone jumps down my throat and accuses me of being ham-fisted, I must say that only the merest touch by the edge of my finger brought it onto the baseboard! Obviously, no problem to refix, but the lack of adhesive between the joint was obvious. So, a warning to everyone - don't sneeze too hard, as you may find something similar happening to one of your models!!!
