Interesting stuff. I actually do not think I am very good at this task. I suppose part of it is a matter of exactness and there is one heck of a lot of nuance in good scents to distinguish them.
One that springs immediately to mind is:
Clubman=Canoe=Pen's Racquets (arguably, on some level, etc.; Racquets is on an entirely different level as a scent from the other two!)
Pen's English Fern=vintage Hobigant Fougere Royale (pretty close to my nose)
I'm going to have to try Canoe, maybe the Pen's too. I've been using Clubman a lot again lately and was curious what might smell similar.
