Picked up a Jungle carbine at a gun show today I believe its a post-war conversion since i picked it up for $230 I have a question is it a post-war conversion? and was it really manufactured in 1943 or was the the year the No. 4 they used to manufactured it. Also did i get it for a good price. Now two more stupid question, first off it take a .303 right? and second question I picked up a pack of 50 rounds of .303 in a bandoleer and the rounds look really, old I will include two pictures Do you think they are safe to use? or are they dangerous to use.
