I recently received an Arisaka 99 rifle from a widow of a friend of mine. My friend was stationed in Japan after WW II and he apparently brought it home with him.It sat in their closet for the last 60+ years until she was cleaning.I wish I could have got more info from him while he was alive.I would like to know as much as I can about this rifle and I thought maybe some of you folks might help with some Questions. 1. From what I have read most Model 99's have a model # on the top of the receiver. This one does not.Is this common? 2.This rifle also does not have a cleaning rod nor a place to store one. There is not a hole under the barrel to slide one in.Is this common?3.There are also little amber colored jewels enbedded in the stock. What could this be?I have included some pictures and I hope someone can help me. Thanks Jim Baird
