Swede & Guys: Got one here, with a curved surface disc, ie: matches the countour of the stock, marked "I 6-- No3XX"...Has the table of corrections nailed to the stock. Stock and Handguard do not match, as well as the bayonet lug assembly, but the bolt and floor plate and the middle band match. IF the one in the auction had a bore condition disc, they would have to cut the inletting flat, to accept the later model flat disc, right?? I will post the pix as soon as I can...Got it at a good price and it is un-fooled with....The bore disc are not usually seen on carbines since most were surplused by the Swedish government without being upgraded . There are probably some that are correct with a bore disc , but more than likely Bubba added it . No way of telling for sure . It has been upgraded with a range plate over top of the decal . So , anything is possible .
