I recently picked up a wak in gunto mounts along with some additional items. The story is that they were acquired on the battlefield. The blade looks traditional but unfortunately has some distress. Nonethless, it seemed like an interesting version. The mounts are fitted for the wak, and not a traditional size gunto. So I am guessing it was used possibly by a tanker. Or it just fit the budget of the officer. I could use some assistance on the signature.
The first photo shows the wak along a standard size gunto. Unfortunately I don't have a great shot of the blade itself with me (I'm traveling in Japan right now). The rest of the photos are self-explanatory. I appreciate any assistance on the name.
