Roger,
I'm very impressed, as I have been before, at how swiftly you recognise different bracket manufacturers and your own brackets, from little features in their appearance.
Could you possibly do a sticky where you indicate the different identifying features?
Whilst this could theoretically enable the fakers to make better fakes - and thus be a "bad thing", I don't think a pictorial guide would raise the fakers' game. After all, a perfect fake is just an identical cast of an original, it doesn't matter what are the features of that original.
A pictorial guide would be useful to us to identify the different brackets.
How about it?
