Photo of 12A Humphreys Building, Kowloon

Hello there: 

I have discovered where my great aunt and uncle Sally and Gordon Castle lived pre-Stanley. They lived at 12A Humphreys Buiilding, Kowloon. I have looked but can't find an archival photo of what the building looked like in the 1930s. Does anyone know of an old photo of this building? 

Thanks very much.
