Rare? German sawback bayonet

[lawrence_n]

Okay, I put the bayonet up for discussion on an military blades forum. I'm now informed that it's an Sg14 as the blade is 310 mm. I'm told that if it was the S84/98 it would have a 250 mm. blade. My question is would the Sg14 be more common or more scarce? What gives the increased likelihood of it being an Sg14 is that would fit with what remains of the makers stamp, "Samsonwerk".
