9/30/21 - This is an original Type 14 Nambu cleaning rod, with an unusual oiler. The oiler is unmarked except for a very small stamp on one of the knobs. This stamp looks like a small MW overlapping each other. The knobs unscrew without issue. We found the oiler inside a Type 14 Nambu holster, so we assume that's what this is for, but we've never seen another like this one. The cleaning rod has dark patina throughout and no markings or stamps.
