To me it's a nice Winchester with a box added. The part with the serial number of the Carbine inside is missing UNLESS I OVERLOOKED IT. The paperwork is strategically torn and gone where the serial is populated. There would've been another sheet identical to the one on the outside that isn't glued to anything, so, where is it?
It's just as likely to be a mix-master shipment someone put an early Carbine with.
Something I've wondered, but isn't as import of a point as the above, did DCM even ship Carbines with type I rear sights?
