Cabela's like some sellers including dealers on some auction sites do not know the rules in a C&R license, it states any gun over 50 years old is C&R eligible.
I have had a C&R license for almost 10 years. I registered for one because my main interest then was L.C. Smith's. At the time they even listed the Marlin era L.C. Smith's from the L.C. Smith Gun Company that were produced until 1968-1971 as C&R eligible even though they were not 50 years old then. They listed the serial number range in their booklet to make it clear.
