Hi there,
I'm no buff, but I've just started working on frame with a Nervex stamped BB shell also from the eary 60s. From what I can gather, the first line of the info refers to the angles coming out of the BB shell and size of the bores coming out the back of the BB shell. Also, are you sure the "f" isn't an "E"?
See attached a scan of the 1958 Nervex catalogue - I've highlighted the spec that most closely matches what you've got.
The number 2027 is most likely to be the frame number - sometimes you'll find this stamped onto the steerer tube of the forks as well - this should match 2027. Don't know if that's a standard convention but it's the case on my frame. You might be able to date it from this - not sure how to do this with Pinarello.
I found the Nervex catalogue here:

Hope this is of interest.
