What series is my arisaka?

I am trying to find out what series my Arisaka is. I think it is a Toyo Kogyo serial number 86432 it has the circle with three circles around it. It is not a series 33 or 35 from what I have seen on the knowledge library. The series mark seems to be a circle with a nearly completed triangle inside of it. It does have a metal butt plate but it has the late war sight and no anti aircraft wings. It does have the Japanese symbols for the type 99 on the receiver. Any help would be greatly appreciated as I cant seem to find out what series this rifle is from my internet searches.

Thanks

These marks are so difficult to identify, that it really would be a great help to have a good photo! For instance, the marks for series 23 and 30 could both be described as a "nearly complete triangle", but they have different orientations. Series 23 has the apex at about 8 o'clock, and series 30 has the apex at about 2 o'clock.

And if it has the 3-cannonballs symbol, but not the "artificial horizon" symbol as well, then it sounds like a Kokura rifle, not a Toyo Kogyo one.

My guess (and without photos it really is a guess) : Kokura Arsenal Series 23. The AA-wings could have been removed at any time, so their absence does not seem to be a reliable clue.

Have you tried this web site?
