I took an M586 in trade about fifteen years ago and it has been sitting in my safe for most of that time. I am enamored of the two 686s I have, but have never paid much attention to the 586.
I'm interested in its pedigree if anyone can help. It is a M586-2 with serial number AZB4XXX. Any information about date of manufacture and what changes were incorporated into the -2 would be appreciated.
