I don't have any pictures of my particular Arisaka, but below is a Wikipeda link which shows it and goes into detail.
My friend did take a video of me shooing it for the first time since I was about 12, but he hasn't sent it to me yet. Below is a youtube video of a couple of guys having fun with theirs.
Shooting it was an interesting experience, one which made me feel somehow closer to my old man than in the fifty-five years since he died, in 1962.
