Here are the photos of both sides of a T-99 maintenance kit wrench, a translation would be greatly appreciated...

Thank in advance, Rick

As stated earlier, the six-character side reads "(gun) barrel stop spanner" so "barrel lock wrench".

The seven-character side reads "trigger guard stop spanner" which I think is just stating more or less where this particular nut is located.

Hope this helps...
