About 10 years or so ago I picked up 2 Model 66's that had been recently imported by Century and were DAO. At the time I think I found a reference that they'd come from somewhere in Canada but I never could confirm anything about that story.
Regrettably both are gone now (and have been for 6-8 years) so I can't give information about the markings other than there were no Department markings or anything like that.
One interesting thing that has stuck with me is even though they were DAO they still had the hammer spur.
Does any of this ring a bell with anyone?
Thanks!
