I think I've been able to identify this razor that I just found tucked away in an antique store by doing some searching around here, but I wanted to be sure. It has the knurling just above the TTO knob and it is gold. It looks a bit silver in the photos, but it is definitely gold and incredibly shiny with no apparent loss of plating. I'm thinking the gold color with the knurling above the TTO knob means this a Gillette Diplomat. I saw a couple other pictures of one just like it, which was also labeled as a Diplomat, and it had the same case as well. So, I'm thinking this is the correct case for it as well. Can anybody confirm or deny any of this? Also, the date code is A2 (2nd quarter of 1955), if that is helpful at all. I'm off to clean it up a bit, there's a tiny bit of soap scum under the head, but otherwise it looks really, really sharp. Thanks in advance.
