There is no difference between the .303 No 4 mk1/No 4 mk1* & No4 Mk 2 barrels. the difference between the models has to do with how the trigger group is attached, barrels are all identical for No 4 mk 1/Mk1* & No 4 mk 2.

They are making new No 4 barrels using Savage .303 drawings from 1940's British loan lease deal. i bought one two years ago, very little machining to breach up. I have put about 175 rounds through it. Accuracy, when you have the ammnition suited to the barrel, is 5 rds within 2.5" circle at 100yds. Mine likes 189gr Prvi Partisan ammo. Good barrels.
