If this is Yuen Long, which Paddy described it as being, I think it must have been on the Eastern outskirts, as the centre was much more built up by 1958.
CORRECTION (2020-05-15) After a great deal of excellent detective work by several readers including terewong, philk and tngan, the location of the old slide has definitely been fixed as been taken close by what is now the Tin Sum Village Office. Readers might find it interesting to read their contributions and see the final Street View image taken from more or less the same spot. The camera used to take the old slide photograph would have been pointing to the West and the scene is a few miles to the West of Yuen Long. Thanks everyone! Andrew
