Hi Craig,
How lovely to have those things

To help you locate the building, I wonder if it is worth you ringing West Bromwich library (I think they have a local studies section) to ask them to look in the historical directories at around that time to see if anything is mentioned - I would think it would be listed at the beginning of the description of the the town information.
I only have directories up to about 1915 on the site I use, but I am sure one of the local studies libraries would hold a range past this date - I've always found the staff at this library very helpful. (Sandwell Archives should have them, too).
Alternatively, if you email the William Salt library in Stafford, as you have a date for the opening ceremony, they might do a look up (free of charge) in the local newspapers which they hold.
Good luck - let us know if you find anything. It's always lovely to hear the end result, Craig.
Hope this helps a little.
Paulene
