Mick,
I could be wrong, but the Nervex number appears short by a few characters at the start - The numbers relate to various original production dimensions of the bracket shell viz ;
??o??64oD222E38
where ;
??0o?? would be the angle between the down tube and the seat tube in degrees - typically 59o30 for 59 degrees 30 minutes.
64o is the angle between the seat tube and chainstays, again in degrees.
D, I presume means diameter, because the next part ;
222 (small 2) is the inside diameter of the chainstay ports in mm.(22.2) with Nervex, whole numbers were associated with
E (Ecart or 'variation') relates to the dimension ;
38 for the distance between the chainstay port centre lines in mm.
With the full number and reference to the excellent Evian (GB) Nervex catalogue reproduced by Chuck Schmidt http://www.velo-retro.com you can easily identify what particular bracket shell was used. I've seen plenty of these numbers that match up on frames with English threaded bottom brackets however no French threaded ones - anyone be as kind as to offer up the numbers from their French threaded Nervex bracketed frame for comparison ?

Hi All,
Any help would be appreciated on dating this frame or deciphering the Nervex
number does it mean anything? Enclosed a message I sent to a friend who is
clued up on this make but any other help would be most welcome.
