Yes a #58 case for sure.That actually looks more like a #58 case (the razor is definitely not a 58), except there shouldn't be a depression there where the handle is sitting, it should be diagonal. I don't know what to tell you about the case.
It may be a British #15 razorHello Community
Anyone knows about this vintage Gillette Safety Razor? Model/yr/worth?
Thank you
Ah, yes. That depression the handle is sitting in is for the blades. Silly me.
