some answers... 1) very rare, much rarer than the lugs, which are still quite available. 2) tho' a stylin' piece, it wasn't as precise in dimension as some would like on their frames. 3) re: answer 1, some builder's may have reserved these bad boys for their ne plus ultra nervex models, rather than cut them loose on every frame built with the lugs. 4) as number 4, it is quite easy to manipulate a normal 70's, 80's type shell to 'look' like a nervex shell. it's easier to 'make' 1 nervex shell than to 'make' 3 nervex lugs. each of the above explanations has affected my use and choices for nervex lug(ged) frames. e-RICHIE
