WW2 Japanese 30mm aircraft gun rounds


#1

Does anyone have any detailed, dimensioned drawings of the three Japanese 30mm aircraft gun rounds: the 30x92RB (Navy Type 2), 30x114 (Army Ho-155) and 30x122 (Navy Type 5)?

I don’t have any of these in my collection and am not likely to get hold of any, so I’m thinking of having replicas made for photographic purposes, turned from solid aluminium and painted appropriately. That’s worked very well for my Chinese 25x183B and 37x240 replicas.
