Wanted to quote this. It is acknowledged by johnone himself that T2 barrels are standard GI barrels that have been shortened and thus should retain their original markings. The rifles in question are completely bare with the exception of the modern CIP proof mark.
"The first type are standard GI .30-06 Garand barrels shortened by .5 inch at the breech end and then re-chambered in 7.62. Those are the T-2
"The second type are purpose made 7.62 barrels marked SIAU 67 or SIAU 68 on the side.Those are the T-1
"I'd be curious to know what type of barrels these German assembled conversions have." The barrels are T-2
"Mine are Springfield Armory made and gauge like new" The Italians used any and all barrels available ta the time. Yes they do look new
