The 1859 carbine serial number range is 30,000-80,000...most have patch boxes. Caliber .52, .54, .56

The 1863 carbine range would be 71,235-99,999 Caliber .52 A C prefix as asked about in that range would also be an 1863

Frank Seller's Book, Sharps Firearms is the most commonly used reference book. Its not perfect, but pretty close. Doesn't provide values, but lots of manufacturing details.

If you want to compare your gun to the book, I will be at Ben Avery this Saturday (pistol sil. range). Let me know, no problem to bring it along.
