I recently received a Type 14 pistol. It is a 19.9 date code and is in 98%+ condition. It came with a rubberized canvas holster and is all matching. It came with two accessories: 1) an additional non-matching magazine, and a bakelite oil bottle. The bottle was in the holster's ammunition pouch and is roughly the same size as the pouch. It is black in color, has a screw on top with a small metal rod attached to it. The back side of the bottle is flat, while the front is curved. It looks like an oil bottle. But to what? What is its value? I couldn't locate anything on the internet. I was hoping someone here could help me. Thank you.
