Need Help Identifying a Cartridge

I need the help of the membership to identify a cartridge. I believe it might
be a Ballard or a Bullard.

Here are the dimensions:

Rim: .630 (thickness is .060)
Base: .578
Shoulder: .534
Neck: .488
Bullet: .445
Case: 1.932
Cartridge OAL: 2.576

Your assistance is greatly appreciated.

Would be close to a 11.43 Egyptian, but rim diameter is small. picture would help.
