The United States government bought a quantity of Model 1854 Lefaucheux Pin Fire Revolvers during the Civil War.  The South also bought them and there were many thousands of rounds for these guns in both southern and northern arsenals at the end of the war.  To my knowledge, there is no way of determining exactly which guns were bought by the South.  This is a model 1854, which would have been bought by both.  On page 97 of the book The Pinfire System by Gene P. Smith and Chris C. Curtis, the authors reveal the exact number and serial number range of the guns bought by the United States government.  I quote "Lefaucheux revolvers was verified exactly as 11,833 total revolvers received by the government.  The serial number range  of these Model 1854 revolvers is believed to be between 25,000 and 37,000."  You will notice that the serial number of this gun is 30756, which places it in the middle of the U. S. government purchase range.  The gun itself has a smooth brown patina with the Lefaucheux trademark on the left frame and the Lefaucheux proof mark and serial number on the right frame.  The gun is complete, except for the ejector rod, which is a very simple affair.  The action works but it has a weak trigger spring.  The grips show smooth wear, but no repairs or particular damage.  SOLD!!
