Arsenal question on my last ditch Arisaka

My last ditch arisaka type 99 is from the Toyo Kogyo arsenal, or so I think. It has a serial # of 305xx meaning it was just past the halfway point of the 57000 35th series that were ordered at the Toyo Kogyo arsenal. My question would be, is this indeed a Toyo Kogyo Arsenal rifle? I do believe it is a 35 Series rifle. It's the mark beside the Toyo mark that has me confused. Perhaps someone can help confirm the arsenal mark on this series 35 last ditch Arisaka. I have read that the 35 th series was manufactured from March 1945 to August 1945 when the factory was bombed.
Thanks,
Rick

Your rifle is Series 35. The mark to the right of could be a bad strike for the second part of the arsenal indicator or just simply post strike damage

If you look real hard on your last excellent image , you can see the bars for the second part. That thing in the center of the second could also be an inspectors mark misplaced...
