Wan Chai Methodist Church

I have been very interested to follow the discussion about Wan Chai Methodist Church. I am a museum curator at Manchester Museum in the UK. I am researching for a new China gallery opening in 2021. I am trying to find photographs of Revd Edgar Dewstoe (1873-1951) who laid the foundation stone at the building of the church in 1936.  He and his wife Sallie or Sarah's  collection of textiles and other objects are now in Whitworth Art Gallery. We would like to show them in the new gallery as an example of  the connections between Manchester and China. One of your subscribers mentioned that there is film of this foundation ceremony. I'd be really interested to take a look at this if possible.
