That is a nice, clean and complete set. I like those models too. I do find them just a little "petite" in my hand but I love the simplicity of the design. Here are my X4-'52 and NDC-'49 versions.
Very nice and thanks for sharing the pic’s. I really enjoy this hobby and the information shared on this forum. Happy Shaves, Bill G
Are clean superspeeds really selling for $30? It's been a while since I've purchased a Gillette superspeed off ebay. Cased examples were selling for about $25-30 then. Loose razors were about $15.
If you like the early Superspeeds then also don't overlook the Black Tip models. They are interesting in that during 1950-51 Gillette used alternative materials for the handles (aluminum and steel) because of the demand for brass for munitions during the Korean war. These models are very similar to the 1947-54 razors providing the same mild and smooth shave. I like the blue cases too.
I like the blue cases too. If I run across one of these that I like I may get one. Thanks for the pic’s, Bill G
