This link above will take you to a website set up by Ed Britton which gives access to some old videos of Sutton Coldfield. One, in particular, from 1931/32 relates to his grandfather, Percy Britton, who was Lord Mayor of Sutton Coldfield at that time. Sydney Stray's tenure as a council officer is also featured.
Ed would welcome any information you may have in this connection. Please contact him via his website.
