Japanese Type14 pistol made in November, 1927 (2.11) by Nagoya.  There was firing pin breakage problems with the early T-14s so many of those early pistols were modified by milling the bolt firing pin slot longer and installing a shorter firing pin to try to correct the problem.  Early examples of the T-14 are scarce but original, unmodified examples must border on rare.  This is an unmodified 2.11 and is also all matching except for the magazine.  There are unusual numbers stamped on the grips and on the mag bottom.  You can also see traces of paint markings on the left grip.
