Maynard 2nd model carbine, my new skirmish gun. 50 cal and 40 gr 3f is the charge it takes in a brass case. this gun is all Original and maybe not fired from the looks under the nipple. If it has only very little. Can any body tell me what the carving in the but stock is. It may have been done by a Civil War soldier. Ser. # puts this gun at being made between 1862 or 1863. you can still see the Inspectors marks in the stock.
