Benser like Bottom plate for 2 lenses

[duckrider]

For a walk in the nature sometimes I don't like to carry my (one of my dozen ) camera bag, but only the F2 with 2 more lenses.
For that reason I built a bottom plate, like famous Leica photographer Walther Benser did construct for Leica M decades ago:

Got myself a set of cheap macro rings and fixed them to a handgrip-bottom plate, have a look:
