Daryl,

Below is are a couple of excerpts that I found via some google searching - r

"Your Sharps rifle serial number 160212 has been located in the original Sharps Rifle Company records of the OLD RELIABLE Bridgeport, Connecticut, plant.

On...March 1, 1879...delivered personally by Mr. Overbaugh to Homer Fisher & Company, Sharps dealer of New York City....Homer Fisher advertized these guns in his (1880)catalogue as the last of the Model 1877."

These records were furnished by the late R.L.Moore,M.D.

"In April 1878 the Sharps Rifle Company delivered the parts for 20 Model 1877 Long-Range rifles to C.E.Overbaugh at his shop on Johns Street, New York City. Overbaugh was to assemble the rifles and return them to Sharps. The rifles were not completed until March 1879....
As assembled, these Model 1877s were classified as Long-Range No. 2s since they have plain wood stock and lack the inscription plate of the No.1. The serial numbers of these 20- Model 1877 rifles assembled by Overbaugh run from 160,212 to 160,240" Sharps Firearms, pp.249-250 by Frank Sellers.
