Llandovery Control Office

[87J]

I am trying to locate any photos or drawings of the LMS/BR Control Office at Llandovery.
I have been through all of the books published on the Central Wales line and I also have a number of Llandovery Station photos in my own collection but no joy - the building stood back from the Up platform and in the most common views of the station taken from the platforms, it is obscured by the water tank on the platform.
This has included contacting the author of the recent book " Llandovery and its Railway", whose father was a Controller there but he does not have a photo either. The LMS Society have not come back with anything.
I assume the building would have been demolished around 1964/5 when services on the line were drastically cut back.
