Picked this set up today and I'm very pleased. This was a lead from a gun show I set up at, and I was finally able to meet the seller and make a deal.
The rifle is nothing special. It's an early 20th series Kokura Type 99 Arisaka. The neat part is it came with papers form the Sailor who brought it home. He live about 2 hours away from me and unfortunately just passed away back in May at the age of 93. He served on the USS Yosemite, a Destroyer tender.
The set also came with a bayonet. There is no serial number and some interesting writing on the top of the handle in white paint.
Here is the gentleman's obituary:
