This strange case was found in an online shop by chance several days ago，and it is different from Russian 14.5×114mm Cartridge.
This is the seller’s photo that compare it with 14.5×114 and 12.7×108，the Chinese character on the photo means “It is bigger than 12.7×108（bottom） and smaller than 14.5×114（top）”，that’s really fun and I can’t get any information or details about this Cartridge case.
Looks like a 12.7x108 and a 14.5x114 made a baby…
Great case! Congratulations!
Can you tell how the flash holes are looking like?
normally factory 41 in this period (60’s to 79’s) use a triangular flash hole “obturated” by a ball who serve as anvil
Thanks a lot for correction，Mr. ammo gun.
Seems your’s here is a Berdan while as Ammogun indicated it also coul have been the “Chinese ignition”, this is why I had asked.
