After some internet research, I have found the info on this rifle. The crest indicates that it is a Chinese Chiang Hai Shek rifle, a m98 Mauser clone. It is identical to the 98 Mauser in that its parts interchange w/ other 98 Mausers.The five point star on the crest means that it was made at the Nan King Arsenal. The 33-8 indicates the year and month. You add 11 to the first number to get the year, in this case 1944. The 8 indicates the month, or August. Most of the Chinese 98 actions were well made and strong.
This particular one has had considerable work done on it. First of all it has been rebarreled w/ a surplus M98 8x57S barrel. it is on a military stock that has been very nicely altered. I was going to change the stock, w/ a Boyd, but the stock on it fits me so well I will just leave it as is. The trigger has been replaced w/ a nice crisp one, single stage, no creep. It is drilled and tapped for scope bases, has a low scope replacement safety, and the bolt handle has been altered for a scope.
I have no fear in firing this gun and will work up some reloads in the 170 grain, 2700 to 2800 fps area.
