Nervex Props are were indeed messy to clean up.. DuBois are just as bad though. I think the shift to DuBois and other simpler lugs was just part of a stylistic trend and had little to do with difficulty to braze, etc. In fact, Nervex Pros were a cheaper and easier pre-manufactured lug that replicated the handcut lugs of the 1950s and earlier.
What Jackie is saying, and I agree, is that there was a second tier, pseudo Nervex Pro lookalike (probably stamped and easier to use) that were used on Motobecane model Jubilee and Grand Record frames in the early to mid 1970s. I think that is unmistakeable when you examine the lugs carefully. This lug patterns are not shown in any Nervex catalogs I have studied either...
