Thanks Giancarlo. Most informative. I'd love to see some photo's of Italianset up 4T's. I don't think I've ever seen one, at least, not that I know of.
I agree with your comments, plus of course, on an original wartime 4T you would never expect to see a Savage rifle with a serial number anywhere near as high as 78C being converted to a sniper. All of the Savage 4T's I've seen & owned have been between 0C & about 15 or 16C.
