Since I have most of them and the thoughts were fresh in my head here's my regular SS collection in a lineup and some musings. This is just my personal rambling disquisition and isn't meant as a competition to Guido's writeup. 1: Ranger Tech the predecessor of all Super Speeds. Made for sale during the X-mas '41 season. Production was curtailed by America's entry into World War II. 2: 40's style Super Speeds. Made from 1947ish-1954 (Z-4). Thought by many to be the epitome of razor design, simple and clean lines. These had a few cases some of which are pictured below. There were a few of what I assume are very early Super Speeds that have Ranger Tech uncreased blade trays, I know of about a half dozen of these hybrids. Ranger Tech, RT/SS hybrid, 1947 SS The first SS's came in cardboard boxes. The '47 not featuring the nifty zip feed dispenser. The red/clear styrene case was the first plastic type Gillette employed. These were available from 1948 until 1950 I believe. 1950 marked the first date code, a prototype V-3. All razors made after 1951 should have date codes. In 1951 and 1952 (W-1 through X-2?) Gillette in an apparent cost saving measure made some razors with aluminum or steel handles and black plastic tips. There were some metal painted tips as well. Not pictured is the aluminum handled black tip. The uncommon 1954 TV, which had Z-3 and Z-4 date codes. The 1953-1954 SS's came in blue and clear plastic cases that are more fragile than the hefty styrene boxes. They will commonly have the spider-web cracking in the clear top. There may have been other containers as well. 3: 50's style Super Speeds. Made from early 1954 until 1957 these are the popular flare tips. From 1954 (Z-1) until 1957 (C-4) they remained the same. The cases were matched for the tips, blue, tan for the silver regular, and red. From 1955 (A-1) through 1959 (E-4) Gillette had a run of colored tips designed for differing beard types. Blue was light or mild beards. Sliver was regular and Red was for heavy beards. Sometime in 1957 the Red Tips got a + on either side on the handle. The Blue Tips have a O on each side. Here is a photo of the high band made from 1954 until 1958 and the lower band made from 1958 through 1959. Gillette had some neat promotions through the years. 1957 Fisherman's Kit 4: 1958-1959 Super Speeds. These had a minor change in the band which was lowered and also lost the screw retainer which was replaced with a crimped retainer. Most SS's from this point on rattle. Gillette made what look like a few trail runs of a later styling in early 1958 (D-1) that for all outwards appearances look like a 1960-1966 SS, I only know of two. 5: In 1958 (D-1-D-4) some had a special handle design and were sold in a promotion with the Gillette Cavalcade of sports, these are the "TV Specials". 6: 60's style Super Speeds were made from 1960 (F-1) until 1966 (L-4?) The cases were white and clear squarer design than the earlier ones. 7: This is the lower head design that some prefer. I can't remember when the switch happened but I think there was considerable overlap for years into 1962. More promotions. 1966 Vacation and Travel Kit 8: The first black handle Super Speed had an anodized handle and can sometimes be discolored (boiled, UV, ect.) grey. These are very grippy. 9: The later Super Speeds have a slicker painted handle and a slightly different interior head design. These came, mostly, wrapped in plastic for hanging vendor displays, but some were probably cased as well. 10: The last versions of this classic mild shaver has a diamond patterned handle, what I like to call the waffle grip. These were made into the early 80's in the US. Picture from eBay I tried to be as accurate as possible. Some of the blade packs are not correct in some photo's. If you have anything to add or correct please let me know I love to learn about this obscure stuff!!
