LMSR Ivatt 2-6-2T 41297 Clapham Junction

From a group of loose prints, many of which seem to be by Michael Brown of Harrogate. This one doesn't have a named photographer.
The number is hard to read - 412 can be worked out from the class, the 9 is just decipherable and 7, which could have also been 3 or 2, is the only one of the three to have been shedded down south at Tonbridge and Three Bridges.
There is no information on the back except 'Clapham Junction'.
