Need a few .50-90 Sharps cases for a project

[Dusty Morningwood]

I have a combination gun that originally had its rifled side chambered for 12.7x44R.  Some Swedish Bubba reamed it out to very close to .50-90 Sharps.  I need a few cases to experiment with before I commit to buying any volume.  Anybody have a few they could sel me?
