I'm looking to backdate my BR Hornby J15 to pre-grouping spec for use on a WW1 layout.
Does anyone have a list of what needs changing?
So far I've think roof needs lowering, different safety valves, stovepipe chimney, Westinghouse pump to be be removed and coal boards on tender to be removed.
Any suggestions for a source of bits to make some of these changes?
Thanks,
Dean
