I noticed this building a few weeks back as I was coming out of the USC credit union on Pulaski Street. You can see a smallish picture with the Harrison sign still up in this Loopnet listing. It also notes that the facade is stucco.
This Allpages listing says the firm was in the "Hydraulic Equipment & Supplies, Hydraulic Equipment Repair & Service, Tools & Hardware Supplies" business.
Finally, this listing includes an aerial shot, and notes that the property is
located in the heart of the Innovista Master Plan
which to me at this point is rather like saying it is located convenient to Hard Rock Park..
UPDATE 14 July 2014 -- This building has now been demolished:
