This has been a razor that there has been some controversy over exactly what is it, how to identify the correct razor to the case, when it was produced. As of very recently almost all these questions have finally been settled. First we start with the year produced. The date everyone seems to agree upon is 1940, as it turns out that is totally wrong. The correct date of production was in December of 1944 and then again somewhere in July through September of 1945 when they show up again for sale. They disappear for good after that point. If there were being sold later you'd see ad space for them around Christmas time of 45 which you don't. Here are the adverts dating this. From newspapers.com Sources The Press Democrat Sun 12/10/1944 The Press Democrat Sun 08/19/1945 The Daily Times 07/05/1945 For some reason I can't put these in as thumbnails so you'll have to view the attached files and if I can make it work I'll upload the 44 ad later on since it won't take right now. Either way these adverts and dates can be corroborated. Now that we know when this razor and set was produced the question now is what was it exactly. This razor was for sure made from leftover parts once the military stockpile restriction on using the left over brass parts was lifted. The first batch in 1944 and then again in July up to September when the war officially ended. After that the razor disappears from the retail advertising record. The only razor produced concurrently with the Regent during this time period for civilian use was the 3pc Tech. All the other brand razors were not reintroduced onto market until 1946 including the Aristocrat. So is this razor an Aristocrat or not. The answer after comparing by shaving it against other razors is no, this razor is made up of left over 41/42 Ranger Tech heads and 41 Aristocrat handles hence it lacking the patient information on the razor head. They also made the Regents with and without end caps, I own 2 that have end caps have been able to compare them against one without and also the 41 Ranger Tech and they are the identical razor as far as the shave goes. No one will mistake a Ranger for an Aristocrat when shaving with both and same holds true with the Regent and Aristocrat. The 41 - 42 Ranger Tech can easily be mistaken for a 44 - 45 Regent Tech because they are the same razor head. The other piece of information is the name of this razor, a Regent is a temporary ruler, if you agree on that Gillette was being precise with the definition then it reasons the razor was only a temporary set until the "king" aka the Aristocrat brand and sets could be brought back to market. As it turns out the first 1pc to have that information stamped on it's head was the 41 Aristocrat another razor we can now prove what it was, what the 41 set looks like and style of razor. Separate post on that. So we can for sure authenticate a Regent Tech razor by simply looking at the base plate if has patent information it is a Regent, if it doesn't then it is an Aristocrat. Pictures to follow.
