Old readers may remember my article and my endeavor to Create Multi Row Panorama Head Ver. II back in November of 2011. Nonetheless, this was already an improvement of an earlier version introduced one year earlier in November 2010. At that time there were very few modular and Arca-Swiss compatible multi-row Panoramic heads around.
Plus the ones that existed were quite expensive, so there was room for a modular solution that would be easy to transform into some other device, using the same rails.
