Thank you that's what I need. Not being an Collector, I didn't really know where to go until I came across this message board while I was searching for information about it. But yeah I'm looking to get the book and not knowing really which ones would be most useful for me, I really appreciate the suggestions! If you have any other books or material suggestions that would be great! From what I did find I was pretty sure of what it was and where it came from. Between the serial number and the differences between it and so many of the other Arisaka's I've seen out here. But the little manufacturer's marks got me curious and there's not really a lot of information out there I mean I figured there's got to be more just didn't know where it might be. and some of those little marks I'm looking at might even just be a little scratches or imperfections in the metal. But it's been an education and a lot of fun so thanks for giving me the introduction!
