New distance scale compared with original ones, font size is bigger for reading, and in Imperial system as well as Metric system upon client's request.
Revised in 4 versions, and re-arranged colors, font size and locations, distance scales are re-designed in whole new looks. Every version of output is different from what I saw on monitor, that took me many hours to adapt with, time wasted between output lab and my studio.
Left two are from original, notice that one in meters, very very few, most 110B I encountered are in feet.
Right four are covered by new distance scales, different scales for different prime lenses, they are more clear reading, and the scale is unified to focal plane, no more confused "Feet to lens".
So do the un-coupled lenses, accompanied by distance scales engraved red line mark, and infinity stop engraves, Byron is capable of with 3 interchanging lenses.
