This is a very early T-14 manufactured by the Nagoya Arsenal.  This pistol was made in the 4th month of production by Nagoya and the 2nd month of the Showa dynasty (Feb. 1927).  Months 1 & 2 were Taisho.  Note the small Nagoya arsenal mark on the right side of the frame.  The locking block on this pistol is mismatched (#109).  The left grip is numbered to the gun, the right grip is unnumbered.  Both grips are arsenal marked.  All other parts match.  The bolt is numbered in a different location than later examples (see last picture).  The magazine is mismatched but has the correct arsenal inspection stamp and is in beautiful condition.
