I have aquired in a lot of other things mixed in an old collection. Now the only thing i am certain of is that both pieces predate 1970 as that is the last time any of the stuff was gone thru... this has been confirmed. Besides that i cannot guarentee any other details... when searching online. The only thing i foind was a confirmed real north carolina but with a different serial number. All the known fakes have a blank back as far as i can see. But the serial i have is common with most fakes out there. However mone has a printed back. Please advise if these are real or not.
