Well the 2A's, aka Ishapores, were produced from the early 60's until I believe the mid 70's. Contrary to popular belief to be designated as a C&R firearm it does not need to be 50 years or older, that is just one of the criteria it can fill.
Here are the two others:
-Firearms which are certified by the curator of a municipal, State, or Federal museum which exhibits firearms to be curios or relics of museum interest
-Firearms which derive a substantial part of their monetary value from the fact that they are novel, rare, bizarre, or because of their association with some historical figure, period, or event. Proof of qualification of a particular firearm under this category may be established by evidence of present value and evidence that like firearms are not available except as collector's items, or that the value of like firearms available in ordinary commercial channels is substantially less.
So the 2A's do qualify as C&R rifles and are sold as such.
Perhaps, if I am very lucky, the feeble efforts of my lifetime will someday be noticed, and maybe, in some small way, they will be acknowledged as the greatest works of genius ever created by Man.
