I have a Sharps I am looking at buying. Its a 1863 carbine and it has double cartouch on the stock under the ring bar. But it does not have sub inspector marks on the barrel or sling bar plate or other small parts. Does anyone know about these marks? I had two Sharps and they had these sub inspector marks on both. Did Sharps make civilian versions during the war? But then how would the wood get cartouch marks on them. Any help appreciated.
