If you have the dies, you can resize 30/06 or 8mm Mauser brass (I think). Graf's has PRVI 7.7 on occasion (sold out now) at the best price.
I noticed you blanked out the first numbers of the serial number. I used to do that also, thinking that's what I was supposed to do. Since 1998, I have yet to hear of anyone accusing someone of stealing a rifle when they saw the serial number on the internet. What does happen is, especially with old weapons, Japanese in particular, the serial number is important to the features on that particular model. As you probably know, the japanese numbered their rifles, to 100,000 in each series. So there will be a duplicate of your rifle's serial number, 13 times for Nagoya Arsenal ("No series" plus 12). For a series one rifle, there wouldn't be any design changes. But for a later war rifle, there were changes even in the same series.
Nice find! Interesting about the missing monopod legs.
