I know of a local RFD who was making quite a 'killing' with Colt SAA's chambered in .41", I believe that this is one of the calibers that was removed? Much as I would love an original SAA the £3K price tag would certainly put me off!
My next purchase (one day) will be an original Colt 1860 Army. Trouble is now retirement has crept up on me, saving £1500+ is proving difficult!
