Vintage Rolls Royce Dealership Technician Tool Mineral Oil LHM Brake Fluid Test Kit

Manufacturer: Rolls Royce

This is a vintage Rolls Royce Brake Fluid test kit that has been sitting in a dealership for the past few decades. I am unsure what years it was used for but as pictured it has some of the original test tubes. The box is made of cardboard and inside is felt coated Styrofoam.
