Yes, a Stroudley design, and a Billington design for their 6 wheel coaches. The LBSC brake ends are the giveaway.
If you squared off the windows of the Hattons 6 wheel coaches they would pass for ex LCDR coaches. Especially if you moved the ducket to the correct position on the end on their brake coach with a touch of 'cutting and shutting'.
p.s. Nice cast iron fireplace in the background - original Victorian or Edwardian?
Ah, I hadn't looked too closely at the six-wheelers, but that makes sense. As you say, the brake ends - and interior arrangement (per 949 on the Bluebell) is distinctive. There will be a second carriage at some point, just not sure what. I'd like it not to be a Ratio four-wheeler, but ubiquity and cheapness are factors... Still 'Sodor' seems like the kind of railway that would have played the second hand vehicle market extensively and I do have a NLR third class vehicle that could be pressed into use, if not much use to potential first class passengers on the Ffarqhar branch...
What this exercise has demonstrated, however, is that some sort of carriage truck is called for (for sir's cars - Sodor Motor Rail?) and probably a second loco' so the five-week old doesn't feel left out. We already have a brake, and loads of wagons which are pretty durable. Excuses, eh?
Yes, the fireplace is probably original so 1880s, we think. The OS revision is 1886? when the house is not present, but it is there in the 1891 census, anyway.
