Sharps 1878 Borchardt military rifle - can anyone identify?

Does anyone know whose initials these are on the cartouches?

Sharps 1878 Borchardt military mint NO RESERVE : Antiques / pre-1899 at GunBroker.com

Nothing in the Sharps book by Sellers

I don't have a clue about the inspector's mark. But that is one FINE looking antique rifle !!

Did you buy it ?? It sold for a nice sum of greenbacks, but I would hazzard to believe it was worth them.

FWIW,
