Hello all. I was able to pick up a replacement from an alternative mainstream dealer that is pristine and it runs like a charm, albeit it needs running in. But thank you for the Facebook idea. Been scammed a couple of times off of there and nothing was local, so I just paid a little extra, for piece of mind. What I will say though, is the train I sent back has simply been put back up for sale with ‘mark on cab roof’ and ‘test run’. Nothing about its horrific wobble/shimmy. And no images of the cab roof. The sale price is as I paid for it in pristine condition so I am a little peeved at the seller/company. Now I’m not going to name them, they were excellent with me, both with this and in the past, but I will identify the train. I believe it ok for me to say, “I once owned this ltd ed. train no. 2043 of 2500, and it needs a cab roof respray, or if it doesn’t when/if you now own it, then it’s already had one.” It’s also the worst runner out of the box I’ve ever seen. However, it may just need a full service/wheel quartering realignment that some of these Elizabeth II’s suffered with. Make sure you test run before purchase. Up until now I have not done anything that ‘might’ effect the value of this loco but with the seller now being less than honest I felt it necessary to identify the problem loco at least. I hope this helps someone someday.
