I'm guilty of both, Daniel.  Yes, the B&W sharpness was a surprise to me, as 
well.  I look forward to seeing how sharp it can be when mounted on a proper 
tripod.

The Ross company was quite capable, and worked closely with Zeiss, 
eventually producing Zeiss optics at a factory in England.  They also 
produced wet-plate and dry-plate cameras as these techniques were 
introduced.
