My Dad's currently building an Alexander Models J27, and it's going together very well. It's intended to be 1056, one of the 1909 Robert Stephenson batch and one of only two that stayed at Sunderland their whole career. Time period is 1930s.
One slight snag is that, other than a couple of photos of it in late BR days, we have no photographs of it at all. The batch it was part of had tenders with three coal rails, water pickup gear fitted, the round-top toolboxes and NER tapered buffers with collar.
Unfortunately, by the time the photos I've seen were taken it had acquired a tender with two coal rails off a different engine and also received LNER Group Standard buffers at some point, but the entry in Yeadons 47B doesn't say when this was done or when the water pickup gear was removed from its original tender. I have mislaid RCTS Part 5.
Does anyone have any ideas? We could probably guess but it'd be nice to know for sure.
