Well since the receiver lacks the type 99 designation normally found under the mum it's safe to assume that your barreled receiver is from a later transitional or last ditch rifle made by the Nagoya arsenal, my best guess is it's from a series 10 Nagoya. Those can be tricky to find stocks for as some were equipped with a stock that had a separate fore end and others had the normal full stocks. As far as the bolt's concerned you would have to find cylindrical styled bolt handle with a welded safety indicator with the numbers 889. The front barrel band should be the riveted type and you would have a short hand guard and a wooden butt plate. Yours should look real similar to this one in my collection, also a series 10 but in the 96,000 serial number range.
