Hey Justin,
The bathroom looks great. The toilet and sink look to be American-Standard Corallin, or Venetian Pink. Difficult to tell for sure from the pics. There should be a manufacturing date stamped into the fixtures, inside the toilet tank and lid, and on the bottom of the sink. Corralin was disc. sometime mid to late 50's when Venetian came out. My old bath was A-S Ming Green, installed when the house was built in '52. Kept the tub (being stored in bsmt. for now), but the sink was cracked, so it was tossed. Toilet had been replaced sometime around '90 when one of my mom's overweight friends leaned back while sitting on it, and it broke where the tank connected to the bowl. Ming was disc. upon the introduction of Surf Green, sometime around '58. Like the tilework in yellow, black and white, too. I'm getting ready to pick out tile for my baths in the next couple weeks, and want to use more than one color.
