HMMM....as the rule is written, Jim, that could be a problem.
Since some had complained of the difficulty of verifying the age of a particular air gun, we decided to go with an "out of production in or before 1986" rule - for the model, not the particular gun in question.
So, if you hold in your hand a particular gun that was made in, say, 1940, but the MODEL is still in production, or didn't go out of production until 1987, or later: that particular gun WOULDN'T qualify.
I do have an Airgun Blue Book which gives production-run years for different models and I'll check this (and any other one in question) out.
