I finally took in apart. I found no serial number on the bolt or under the hand guard. Under the handguard on the barrel I did find what looked like "R 1 0" or maybe the "0" is a 2? On the flat part of the underside of the receiver it's stamped N S, with J J 100 underneath it. The first "J" looks almost like a mis-stamp/double stamp because it's alot lighter than the "J" closer to the 100. I also found what looks like a "98" stamped in the stock.
Here's some pics, what do you think?
