Re: Arisaka Type 99 Rifle...
One sure sign that it's a late model is to look at the safety on the end of the bolt, if it's knurled, it is NOT a late model. I have yet to see one without knurling that was a last ditch and vice versa. I would agree with you that you have a earlier version from your statements. Vast majority of 99's were 7.7, but it would be best to have this confirmed by a gunsmith, if you can't tell. Ammo is available from Norma; it is also not hard to find components for reloading either.
