    Sharps made a number of rimfires...

    I found a 45 (2.1") Sharps Straight Wall that's close but I don't see that it was a rimfire.

    Listed as .458 / 2.105 case length / rim .608 / case mouth .480 /base dia .500 / LOA 2.43

    I'll forward you the resource I found.

    Sounds like a .45-70 with one of the various patent inside priming systems that kind of fill in between rimfire and centerfire with external primer cups.

    possible ID

    [probably] a Benet primed .45-70 round. These were designed in the late 1860s by Colonel S.V. Benet at the Frankfort Arsenal. Used in U.S. military handgun and rifle cartridges, the system involved a copper or iron cup that was crimped inside of the case head. The cup was actually an anvil, which allowed the firing pin to detonate the priming compound. These are fairly common, but they do still have collector interest, the value of which depends upon configuration and markings--or lack thereof. Five to $10 apiece is about average.
