If this is the case, the following reference may help in dating:Looks a possibility, I suppose we will have to wait to see if Mike was ever in Solihull.
I decided to have a look at gasholders on 'britainfromabove' and typed 'Gas Works' into the search box and 1073 aerial views from all over Britain became available on my screen. Looked through them all and saw many very good images of gasholders in small towns around Birmingham but unfortunately not the gasholder and buildings in Mike's photo.

The Solihull Gas Works had been established by Solihull Gas Co. in 1869 and came to supply the local area.
They had absorbed Knowle and District Gas Co. in 1935, and during the mid-1950s had taken over the supply to Henley-in-Arden. The demands of supplying the nearby Shadow Aircraft Factory had resulted in complete reconstruction of the gas works with vertical retorts.
Solihull Gas Works were closed in 1962, the year before a new gas-making plant at Coleshill was commissioned.
