I acquired a Howa carbine a while back, in excellent condition. Royal Thai marked. It's now my shooter to keep me from shooting the more collectible ones! I know it's not USGI, but has anyone got an idea what magazines were supplied by Howa for them? I've never seen mention of them. I've seen some Plainfield mags marked "Japan" but I doubt that's what went to the Thais, unless they got GI mags...
