Yes, we do have old city directories in the Central Library. The following listing was found in "Polk's Pasadena City Directory 1956" page 755
THROOP GEO L CO (Geo L Throop & Geo L Throop Jr), Building Materials, Plastering Materials, Brick & Concrete Blocks, Concrete Colors & Waterproofings, 204 W Holly, Tels SYcamore 6-3155, RYan 1-6427
There is no Troops (or Tromps) Building Materials found in the directory. I was also able to find some information on the George L. Throop Co. from our vertical files.
