The secomd shot is of one of the NBL built 25nc's - the diamond worksplate is visible under the number plate.
The picture earlier of 3511 under the threatening clouds is a classic - I was never fortunate enough to see it but, I think, I saw the other remaining condensor(3481?). My only view of a 25NC in steam was one shunting (with daschund tender) at Kimberley though I see the preserved 3405 (in the UK) regularly - It'll never steam.
