I bought this gauge close to 15 years ago, don't remember what I spent, who made it, or where I got it from. Tried to use it a short while ago, and didn't have the greatest experience, probably because the piece wasn't clamped (I was just trying out the gauge after a long while). The blades could use a bit of help as well, will be getting to that.
My Kanji skills are non-existent, but perhaps someone can help identify the maker.
