Wool & Skin Merchants Industrial Building - Launceston

I love the dark red brick of this former industrial building, and the fact that the original business name still exists on the top of the building 'Wool & Skin Merchants'  The original steel frame windows with that non-transparent glass are so typical of 1930s-1950s design asthetic.  I notice that when a window smashes in such buildings it's more often than not replaced with transparent glass.  I imagine that this glass isn't made anymore, or it would be expensive to reproduce.  I love the small details like the original windows as they play a central role in retaining the buildings original design aesthetic. Without such features the original visual language of the building would be harder to read.
