Yes, those boxes are French and also likely corrosive, would not shoot it. The one round pictured with the TW 43 head stamp is interesting, TW is for Twin Cities Ordnance Plant but I personally was not aware that this plant produced carbine ammo during WWII, and it is not listed in any of the Ruth books, so I would say the TW ammo may have some collector value. Post a picture of your LC 52 but I do not believe that the Chinese LC 52 ever came on stripper clips, do you have any of the bandoleers? See the below links for some more info.
