I found a Berthier made by MAC in 1917 (October 1917 on the stock). It's all matching, bolt, bolt head, barrel trigger guard and cleaning rod. It also has a great bore. The carbine is something of a time capsule as it does not appear to have ever been rebuilt. The stock shows no signs of ever having been fitted with a handguard, there is no cut for the rear ring shaped band. The center band is not the sort which would accept a handguard either. The five shot clip extension does not have a serial number. My question is, did the French make Mle 16 carbines without handguards for a while? Thank you.
