The Rolls Razor company offered 3 types of “Imperial’ razor sets - #1, #2, #3. The differences were based on the material used for the case and lids. This example shown here seems to be the most common – the #2. The case is, I think, nickel plated brass.
Notice the lid has 3 rows of the Greek Key design. The later models only had 1. Earlier models did not have this design on the case.
