It wouldn't interest me. If it was a pre-AE, pre-safety shooter with some character, then I would be into it. I traded away a 70's Marlin 336 in .35 Rem. and now I'm keeping my eyes open for another one. I'm liking your rule more and more as I get older.
To a much greater extent than most mechanical devices, firearms are terribly unforgiving of any overconfidence, complacency or negligence.
