It's just the way it was made.
A beautiful phonograph!

Dear Andreas,alang wrote:Enrico, don't the pictures 123 and 124 from the book or catalog also look like the arm was a bit short? Could it be that they were made this way, maybe caring more about the beauty of the case then proper tracking? It is a beautiful machine for sure.

Thanks James, I also agree with Andreas' suggestion.Roaring20s wrote:I think this is the answer.alang wrote:Enrico, don't the pictures 123 and 124 from the book or catalog also look like the arm was a bit short? ...

Grazie Marco.Marco Gilardetti wrote:I agree that the arm featured at page 124 will also never get to the spindle. They were probably careless about tracking at La Voz De Su Amo.
Leave it as is: gramophones with HMV'S tapered tonearm - gooseneck - Exhibition soundbox combo, all have horrible tracking geometry anyway.
Caro Enrico, you will find many interesting pages over the internet about this subject, however you will find a "vintage" essay on this book, which was fully scanned few years ago:Enrico wrote:Are there any documents to learn more about tracking geometry?

The subject is treated from page 121 onwards. Not coincidentally, in figure 48 the HMV tapered tonearm with gooseneck is taken as an example of a "careless" tonearm with no attempt at all at correcting the tracking error.
Another extremely interesting webpage is that by the late Graham Barber - whose death and whose gone website will be never mourned enough in my humble opinion. There is a series of pictures by the end of the page in which tracking error of some gramophones is shown by using a protractor. The HMV tapered/gooseneck is exemplified by a HMV 100 model (top-center). You should be able to see this "photograph" of his defunct website taken by the Wayback Machine archive:
