Here are four different versions of the nib guides that Parker issued.
First is a dealer nib display for the Parker VP, the pen that pre-dated the 75 and introduced the idea of rotating nib to suit the handwriting style of the user. This is the feature upon which the 75 was marketed when introduced in 1964. You can also see quite a few similarities between the shape and numbered sizes of the VP and 75 nibs.
The second is a brochure, which is specific to the 75 US-made 14K nibs. Notice that the 75 introduces five new sizes that the VP did not have. These were:
68 Extra Broad
69 Fine Stub
72 Extra Broad Stub
97 Fine Italic
98 Heavy Italic
The 75 line also changed the names of certain sizes. In fact it appears that 70 and 73 swapped sizes:
70 went from Thin Music to Medium Stub
71 went from Stub to Broad Stub
73 went from Stub to Thin Music Stub
The third is one that was released in a product catalog in the early 1980s, and the fourth is from August, 1991.
Here is a better look at the writing sample for each nib.
