Six jours:
here's my Clubman, as it was when I got it; notice the celluloid mudguards, broken and missing several pieces. The "spearpoint" shape of the front mudguard is distinctive; I think somewhere out there on the innerwebs you'll find instructions for cutting Bluemels fenders to imitate it.
Sadly, I haven't had time to finish the Clubman yet (my other bikes keep demanding attention from me), but I got some NOS white Bluemels Club Specials for it. Back in November, when I bought them, the guy had one more pair left.
