The designations were done over 10 years ago and I assume Appleby did them in order of how he discovered each through his own research. That information hasn't been updated at least 10 years and the sites out there now are copies of the original information since Appleby's orignal website with the injector information is no longer online.The M1 didn't have the guard/blade lock? - I might be incorrectly referring to my M2 as an M1, as it does have the switch to raise the guard to block/protect the blade edge. (Great feature for traveling, it keeps the blade from getting dulled by hitting anything else in your bag).
Why did they age them in that order, the M2 is really newer than the M3, using the above chart. - Oh well
The dial on the M1 and M3 are identical marking wise. That is what happens when people copy information verboten. The only the sticker on the handle is different.According to this site (razors.click - Schick Identification - https://www.razors.click/safetyrazors.net/SchickTech/), the M1 has "Schick Dial" on the handle, and no dot on the dial. The M2 has "Adjustable by Schick," with dot and cross on the dial. The M3 has a black dot on the dial and "Schick Adjustable " on the handle.
That said, I think they mixed and matched parts. My Schick Adjustable came in a yellow blister pack with twin injector blades. The dial-side looks like the one in the photo, but it has the blade guard, which moved the safety bar up when the razor isn't in use.
It still would qualify as an M2 since M2 razors were made from 1973 to 1982 and it has the blade guard on it. Very possible if it is a foreign market razor they recycled old stickers and such on the razors there. Gillette for example would sell discontinued excess inventory of parts and fully assembled razors for discontinued US made razors years afterwards in foreign markets like Australia. I wouldn't be surprised if Eversharp / Warner Lambert did the same.My Schick Adjustable has the following:
1. Dial and lettering as seen in the first photo.
2. The Protector as seen in the second.
I also clearly remember that it came in a yellow blister pack with twin injector blades. I purchased it at a discount store, and debated whether to buy that razor or a DE. Time was in the mid 1970s.
I've never tossed a non-disposable razor, but what kept me going back to this one was that blade guard made it ideal as a travel razor. Just close the guard and put in my toiletry bag. I stopped that only when I realized it had become rare, and didn't want to lose it. Went back to it several years ago.
That information is the same old outdated stuff.This has to be one of the most updated and accurate timeline for Schick razors. I have to agree with @BBS-1 that your razor looks like a M3 like the one I own. You are going to be one happy person using that razor IMO.

That first incarnation was a prototype with that big metal or plastic dial. It was never sold to the public.Go here and scroll down for what one collector says was the first incarnation of the Model M:
Just scored this on the bay. Injector has 1 unused blade in it. Near mint with instructions and case. I put it at 1966 to 1968. I'm a sucker for...theshaveden.com
