Jim, does the book distinguish which ones are correct for WWII? Bando's website inicates only the bone handle knives at a certain length and w/o patent numbers are correct. Yours looks just like the ones in the box. I have the second type also without the patent numbers and the blade is marked like yours but with the bale. You have a very nice example. They are very difficult to find and pricey.
