I will defer to any other Jag owners who may answer this, but generally
speaking, "Near Side" is the curb side or passenger's side of the car, in 
England anyway, which is the left side. Hence the slightly redundant 
"Left Near Side". The opposite would therefore be "RIGHT OFF SIDE". What
puzzles me here is that (going by my experience with my uncle's Alvis),
the right/left labeling is required because the threads go in opposite
directions on opposite sides, since obviously the wheels are turning in
opposite directions and you want to keep the knockoffs tight. (The same
logic applies to the threaded pedals of a bicycle.) Therefore, I don't
know how you could manage to get a left-side knockoff even remotely
secure on a right-side hub.

More likely, the knockoff just wasn't tight enough. The Alvis came equipped
with a brass-headed mallet, which you used to apply several brisk whacks to
the ears of the knockoff once it was seated.
