A Purity Flour Mill

I have a number of photos taken by my uncle, William Henry Wood, that have no notes indicating when or where they were taken. With these I've had to make some guesses based on where they appear in his collection, and from what little I know of his travels as an auditor with Purity Flour.

My guess about this Purity Flour facility is that it was located somewhere between Winnipeg and Calgary, and these photos were taken sometime between September 1943 and September 1944.

Needless to say, this is a huge operation.
