Congratulations! This is a great resource. And it reminds me that I too should get busy writing my own guide for Ben Wade pipes.
One recommendation I'd make--a point of constructive criticism--is to try to include attribution and sources in your guide. I noticed there's a guide on MBSD to dating Barling pipes:
"Dating Barling Pipes: A Three Step Guide." There's also a guide on Smokingpipes
"About Barling Pipes: A Pocket Guide." With the exception of mentioning Tad Gage in the latter, neither offers any indication of where they got their information.
I'm almost certain that the author at MBSD (whoever he was) drew from the research of others, notably our friends Jesse Silver, Jon Guss, and Tad Gage, who spent years doing the legwork and tracking down primary sources, just to offer us this information as a guide (for free) on Pipedia. It's certainly plausible that the author drew from other sources as well, which, if so, would be good to know.
In matters of scholarship, it's generally considered common courtesy and best practice to give attribution to the sources you draw from and to cite any references/sources accordingly. This gives credit where credit is due, and it also augments the authority of the work by buttressing it with factual evidence.
Congratulations again!
