Hey everyone so, my grandfather recently gave me a japanese arisaka type 99 chambered in 7.7. the problem is this arisaka has been sporterized (new and bent bolt handle, sport stock and scope added. I really want to convert it back to its original version which will include stock, bolt handle, no scope, original boyonet (if i can find it) original steel sights). my rifle does have some rare items the mum is in tact as it was captured during the war all the markings are clear as day the metal is in perfect condition, the safety is of the decorative type unlike the late war type. so my question for everyone is, is it possible to unbend the bolt handle? where to find original parts and what parts have numbers on them that need to match? thanks in advance for any and all advice and answers.
