Unknown: History of this Building Please

Unknown: This building, now under new ownership (an antique dealer) was apparently once a truck engine factory in the WWII era.  It just has that 1930s look to it.  Unfortunately, I know very little else about this building so any information is helpful.  I've wandered through a few times, and, the word is the current tenant is temporary until the building gets ripped down as part of whatever plan the city has for the City Centre.  It's worth going to have a look inside this building - the old wooden beams are pretty cool.

On the other side of the building, I snapped a few images where shadows worked their way onto some construction materials.
