CR, in my recent posting about the 1952 Charles Pelissier randonneur
see http://www.peterbrueggeman.com/
I puzzled in my email over an alloy nut on the left rear dropout. Leonard Bulger (Marblehead, MA) pegged it as a threaded hub skewer. Yes, unthread it and the hub/wheel falls out of the vertical dropouts, leaving the freewheel still attached in the right dropout. I had tried it by hand but it took some pliers to nudge it along.
