Unknown Vintage Handgun Cartridges

[Dillinger022]

Hey guys,
I need help in identifying the calibers and makers of the following three vintage handgun cartridges.

I've determined this to be a 9x23mm Steyr cartridge.
-Headstamp: H = Hirtenberger / 1934
-Rim diameter: 0.38 inches (9.66mm)
-Rim thickness: 0.048 inches (1.22mm)
-Case diameter: Same as rim diameter
-Case length: 0.902 inches (22.91mm)
-Cartridge length: 1.297 inches (32.95mm)
-Bullet diameter: 0.355 inches (9.02mm)



I've determined this to be a 7.63x25mm Mauser cartridge.
-Rim diameter: 0.393 inches (9.99mm)
-Rim thickness: 0.043 inches (1.11mm)
-Case diameter (near rim): 0.389 inches (9.89mm)
-Case length: 1 inches (25.40mm)
-Cartridge length: 1.373 inches (34.89mm)
-Bullet diameter: 0.301 inches (34.89mm)



I've determined this to be a WW2 Japanese 8x22mm Nambu cartridge.
-Rim diameter: 0.411 inches (10.45mm)
-Rim thickness: 0.039 inches (0.99mm)
-Case diameter (near rim): 0.405 inches (10.29mm)
-Case length: 0.837 inches (21.27mm)
-Cartridge length: 1.242 inches (31.56mm)
-Bullet diameter: 0.319 inches (8.12mm)



Thanks, guys.

9mm Belgian Nagant-Frommer has closest dimensions

Second one closest to .30 Luger.

Third is hardest to pin down. One of many 8mm Bergmann calibers.

Not so esoteric.
1. 9x23 Austrian Steyr
2. .30/7.63 Mauser/Borchardt
3. .30/7.65 Luger (might actually be an 8mm Nambu, but primer doesn't look right)

Thanks, guys!
The 3rd cartridge down definitely is closer to 8x22mm Nambu in dimension and it's lack of a headstamp is also consistent with WW2 Japanese 8x22mm Nambu production.
