Sword and Shield

GG owned/had made the Sword.  Did SS have the Shield that LV used 
dueling DD?  The shield pictured at the begining of "The Only One He 
Ever Feared" in OoP (hardback US edition)has a snake on the shield 
though there is no physical description of the shield in the chapter 
except to say that it's silver (one of Slytherin's house colors but 
not exactly an uncommon color for a shield)
Canon says the shield was conjured, but there are different 
conjectures as to what that means.  Did the shield already exist and 
was merely teleported to LV, or did LV merely change thin air into a 
shield? 
Could LV/TR have found and taken the shield from the Chamber of 
Secrets?

Apologies if this has been discussed.  Somebody please direct me to a 
message post number.  Thanks.
