An other one would be is MN-59 which is a MN-91 or MN91-30 cut down to 20 1/2 inch barrel. Only exterior difference between a 59 and 38 is the barrel dia. In 1959 The sattlite countries started do this for there police.
Talk about kicking your self, about 15 years ago, I saw a Enfield in 7.62 X 63. for 30.00. Went home and converted 7.62 X 63 to what it was (30-06) Come to find out there were 50 made or converted to 30-06 and 50 to 7.62 X 51 (.308) When back the next morning and it was gone. They still had ammo in 7.62 X 63 in lower pressures, but it was gone in a week.
