Yes, the roll engraving sounds like a Spiegel (Salesman's Sample) rifle. These are a none cataloged version.
Lets clear up the date. What is the serial number (first 4 or 5 numbers will work). For the date you gave most only had the butt checkered.
Is it drill and tapped on the barrel behind the rear sight and one hole on each side of the cocked indicator on the tang?
Is the front sling swivel used to attach the forearm or is it in addition to a forearm screw?
