You are probably mistaken.
I have confirmed with Car and the fatboy (which you probably know as well) can acutally replicate 100% Ambrosi workmanship.
The replication contained, inter alia, the followings:
1)Triple curtain waistband
2)Hand tag on all pleats and pockets
3)Full on hand stitching in all attachment areas
3)Side seam of trouser also hand stitched
5)Two internal lock button and four button fly
6)all hand sewn buttonholes
7)Light and stiff waistband canvass
I know of the member had went a long way to ask fatboy to do it. He actually has a Ambrosi Trouser and passed to fatboy for replication.
Obviously, I asked about the price and turn out time for these extra work... I just have not pull the trigger yet.
