Learning curve - feet Two

The original Marchioni foot (left) had a descending spike through a fixed rubber tip.  The foot in current production follows  the opposite design - a fixed spike with a descending rubber tip - a change in design that I believe occurred with the Marchioni brothers before they sold the company to Leitz USA, but a design that certainly exists on the later Uniphot version and the StarD version.  If you own a late Marchioni, Leitz or StarD Tiltall, kindly submit a foot jpeg to correct this post and for the edification of your fellow aficionados.
