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.

While Central Library is closed for earthquake retrofit and building repairs, contact staff at any branch location, and we can assist you further.
