Thanks everyone who has offered advice so far. My first port of call was Bob Essery’s and Stephen Summerson's fine books to make notes. Then I waded through my sets of Midland Record’s and LMS Journals, nothing in either for what I needed.
I’d best explain what I’m doing.
I've been eyeing MR 2-4-0's for a while for my 1905/6 period S7 layout, but the question was which Class – as I’m not that well versed on Order and Drawing Numbers etc. I tend to describe MR locos by class. This approach I will admit doesn’t work when looking for drawings for an engine that I know as a ‘1400 Class’. So thanks every one for your understanding.
Looking through Summerson Vol.3 I can’t find any Drawing Numbers quoted for the 2-4-0’s.
Originally I considered two classes, the 1400 (6ft 8½ inch wheels) and the 1492 Class (7ft wheels) and as it is to be scratch built I needed at the very least a GA for the engine and may be one for a tender, but that’s another matter.
Judging by what information there is available out there, research is dictating this, my engine will need to be a 1400 Class with 6ft 8½ inch driving wheels.
As for the ‘date’ of my engine, it would need to be as seen running in 1905. I haven’t as yet chosen an engine number, however it’ll be from one of the three batches built between 1879 and 1881.
For 1905 it’ll have the revised full sweeping reverse curve design of splasher. As for the boiler and cylinders, Summerson’s book appears to show all would still have had P boilers at that date, and all which hadn’t got them had 18 inch cylinders fitted by 1905. So that makes life a little easier.
Hobbyhorse’s drawings seem to be what I need, would you be happy to let me have copies of the 6' 9" version GA and the cab and smokebox drawings? I take it when you say 6ft 9inch you mean 6ft 8½ inch driving wheels.
Cheers
Tony
