BriP asked me about a Blade Nosepiece that wasn't quite fitting onto a Blade lens. Got me wondering about the various nosepieces that we have from Blade to Modern M Frames.
Blade:
Slit:
Zero:
Odd Sub Zero:
Older Style M Frame Kit:
Newer Style M Frame Kit:
SI M Frame 2:
Almost seems like there was a smaller style just after shrinking from the Blade/Mumbo to the Modern 'pointed' M Frame nose piece, were it was still flatter, but also smaller. The SI M Frame 2 also did away with the pointed form.
