I was surprised at the lack of info about this...maybe I'm not using the right key words.
Your comment brings an idea to mind.
It sure would be great to have a chart of lugs by brand with their model names, catalog numbers, and specs available.
All that info is in different books, on our own Drum Guide, and other sources, but to get it all compiled in one place would be a very helpful resource.
There are a couple or three industrious researchers that post here, perhaps one of them will pick up the challenge?
As long as the sources are cited and referenced there shouldn't be a problem with using the available outside sources and posting them on this website?
For instance, on page 198 of Rob Cook's Ludwig book, there are twelve illustrations from the 1976 Ludwig catalog of lugs with specs for each one.
Something like that for each of the major companies might be very useful, and an easy answer for those who pose the question as you did, (and that question is posed pretty often) ... they could simply be directed to the chart on this website.
