I just found my first 2 DE razors at an antique store. I got a 1957 Blue Tip Super Speed and a 1960 Slim Adjustable. I got them for $12 each. Maybe a bit pricey, but what I was seeing on eBay with shipping wasn't too different. Plus once I got them in my hand, I had to have them. I am very impressed with how they look now that I actually have them in my hand. They cleaned up very nice. I just need to go get some polish to get them nice and shiny.
I'm impressed with their weight, especially the Slim. I also had a very strange feeling when I looked up the date codes. (C2 and F4(edit - correction L4)) I just had an overwhelming realization that what I had in my hand was older than me and almost as old as my dad. Yeah I read about 1940s this and 1950s that, but really that was just a number before. Now it is an actual length of time. Those things are over 50 years old!!! and they are amazing little pieces of engineering. I appreciated the mechanical design of them and how the TTO worked. I just love that.
I will post about my first shave with them later.
