The Nambu is a semi-auto recoil operated pistol chambered for the 8 mm Nambu. It has a 4.7" barrel, an 8 shot magazine and wood grips.

The value of a Nambu Pistol is determined by the date of manufacture and the arsenal that produced it. To determine the date your gun was made look for a 3 or 4 digit number just forward of the lanyard ring on the right side of frame (on back of grip). Earliest Taisho era pistols are dated 15.11 or 15.12 from the Nagoya arsenal - can be identified by small trigger guard and other early features. Fewer than 100 mfg. To determine year and month of manufacture for most type 14 pistols, add "1925" to the first two digits and the last number will indicate the month (i.e. code 13.3 indicates a gun built in March of 1938).
For guns made between 1925 and 1930 the Blue Book values are:


For 1930 to 1939:


For 1939 to 1945:


Add 10% for strawed trigger and safety.

For all guns add the following:

Add 25% for 3.X date Tokyo.
Add 50% for 2.X date Nagoya.
Add 400% for early Taisho era pistols dated 15.11 or 15.12 from Nagoya arsenal.
Add 10% for matching mag. on models listed.

Add 20% to 30% to the Blue Book values for retail prices.

The price for the original ammo is all over the place. From $4 per round, $130 per box up to $250 for a box.

There are boxes of new manufacture available for $42 for a 50 round box.

I hope this helps you,
