Hi - I'm hoping someone can help me with some information regarding a Spencer carbine that I have. The serial number is 10519. It has the Springfield Armory cartouche on the left side of the stock indicating a return to the armory for repair. As it is below the published starting range of 11000, does anyone have any information as to what it might be? Perhaps one submitted for evaluation or ???? Does anyone know where these early ones were issued to? I did exchange emails with the author Roy Marcot a couple of years ago. He indicated it was the lowest carbine serial number they knew of but, as he has gotten away from Spencers, he was unable to provide any additional information. Any help would be much appreciated. Thanks!
