Everyone loves the beautiful Nervex lugs. Looking into the literature raised a few questions. As I was only to find one old brochure I figured I should ask here.

The 49/192 prefessional lugs, did they make something other than that? say, perhaps, a 49/191 or a 49/193 or was it exculisively a 49/192 set?

Angles. Is it safe to assume all 49/192 lugged frames have either a 72 or 75 degree head tube? In later years did they introduce new angles or where frame builders forced to use a different lug set if they wanted different angles?

Does anyone have links to Nervex catalogs? I found this nice article:
