This post by Robert Messenger piqued my interest over the Mercedes serial numbers in the Typewriter Database. They had not yet been updated with the newest information from Source #24, and so with Mr. Messenger’s post in mind regarding the K-45 “Superba/Selekta” issue, I delved into it.
This is what Dirk Schumann had compiled from Sources #7, #10 and #13, and it’s what I started with in my update. I don’t actually have access to *any* of the three sources Schumann used in compiling his data, but I *do* have Source #24, Schramm ’62, which is an updated edition of #13. This is what I checked against to verify Schumann’s data.
Let’s look at the Source #24. This is a composite image of the relevant section, and it shows quite clearly that the K45 is called “Superba” and the K50 is the “Selekta”. This seems to confirm that Schumann didn’t just copy it down wrong, and it suggests that Schramm didn’t feel the need to correct the names in the 1962 Updated edition from the 1955 edition even though quite a bit of new updated information *was* included in the 1962 edition:
So there it is. Mr. Messenger’s source is Leonard Dingwerth’s “Die Geschichte der Deutschen Schreibmaschinen-Fabriken” and Ernst Martin’s “Die Schreibmaschinen und ihre-Entwicklungsgeschichte” (Source #4), neither of which I have access to to confirm, so the debate will continue as we try to work out which model names belong to which model numbers. :D
