If you collect Japanese Military Pistols this is your “Singer 1911a1” This is an extremely and elusively rare Hamada Type 2 Pistol is 8mm Nambu Caliber. Less than 10 are known to exist and this one is right smack in the middle of Production at serial #25; its slide frame and magazine all bear that number. Number 28 sold in 2019 for 30k at auction. This is a textbook example, they are all in the white, never having been blued.
This is the 2nd Pistol designed by Bunji Hamada and produced during WWII. The type one model was smaller and in .32acp and about 5000 were estimated to have been manufactured. Late in the War Hamada designed this pistol to replace both the type 14 and the type 94. It is a much better pistol than either of those models and had it been produced in any significant numbers it would be well thought of. I hardly need explain the history or the intricacies of this pistol to the very advanced collector who will want to acquire it for their collection.
This pistol only recently was discovered in the past year or so, it came out of the woodwork in the midwest, having been brought into a small gun show, so this piece is newly arrived to the collecting scene.
