Daryl,

I think we should start out covering the American doubles(and singles) as those are the ones that offer the fewest clues.
I am not sure what order to gather data or the best format for presentation.
I have sizable picture files that have rib pictures of many of the American Makers.
Drew's work on the Damascus patterns also has detailed views of the top ribs.
My OCD (CDO, alphabetical as it should be) makes me a stickler on detail differences but my presentation skills are nonexistent.
I am still working so time for research is very limited.

Any suggestions?

John
