Check the 75x185R and 75x294R shrapnel projectiles in the attached pictures; as far as I can tell from the pictures (that is: without walking up to the actual rounds) all of those have the Type 3rd-Year fuze, this has a time scale that goes to 22 seconds. Same for the 105x243R HE-Substitute round; it too has such a fuze. Incidentally, you can see both it's predecessor and it's successor too in the pictures.The former being a much older kind, having a scale going to only 18 seconds. I don't know a Type number of it, but the earliest specimen I have is from 1901; well before the Type 3rd-Year fuze was accepted into service (3rd-year = Taisho year 3 = 1914). These smaller fuzes can be seen on the 'short' 75mm shrapnel projectiles. The successor of the Type 3rd-year fuze, being the Type 5th-year fuze (i.e. acceptance: 1916) has a time scale running up to 36.6 seconds. It is taller than the Type 3rd-year fuze and it can be seen on the two 105mm Shrapnel projectiles.
For all mentioned rounds/projectiles: check the legend below each image (and correlate that to the numbers in the pictures) for checking which item is what. :P
