Is there any general resource on the development of lug patterns, esp. post-WW2? I've been trying to ID the lugs on my Viking, primarily by staring at Sheffield's, Dale's, Bob Reid's, and Joel Metz's galleries. What's interesting is the similarities among the early Nervex, Prugnat, and Oscar Egg lugs, which hasn't helped me pinpoint mine. They'll probably remain mystery lugs, but it's fun searching around.
