Something pretty strange about that thing.   I have lots of experience 
with two-speed axles in GM trucks.   Both vacuum shift and electric 
shift.  One of each are still on the farm.  A '56 and a '59.
I learned the two-speed in our 51 Chevy and 52 International and  I 
don't recall any of them getting in neutral with the engine off.  Too 
cold to complete a shift, YES!  Bad news when climbing a hill.  Because 
of that, we usually parked them in high in cold weather.  Maybe you had 
a different brand, or maybe we just didn't know they could slip into a 
neutral position unattended.  I am a flat-lander, if that makes any 
difference. ;-)
    My Dad's 51 Buick and my 36 Chevy both had the footfeed starter.  
Once started, the vacuum kept the footfeed from engaging the starter 
function.
